Energy Harvesting SIG Energy Harvesting Capability Map Special Interest Group Energy Harvesting January 2014 The Energy Harvesting Special Interest Group The Technology Strategy Board has launched its Emerging Technologies and Industries programme and is working with partners to build a UK programme in Energy Harvesting. The programme is intended to accelerate the development and commercial use of products, processes and services based on energy harvesting technology. The Energy Harvesting Special Interest Group (SIG) brings together the community along the value chain – from academia, materials technologies, devices, systems integration and through to the user communities helping build a vibrant and productive Energy Harvesting community in the UK. The information in this report will be used by the SIG to widen the debate about where energy harvesting may have a role to play. It will also provide input to briefings for funding agencies on challenge areas to be supported.

This report covered both academic and industrial communities. Energy harvesting research is very strong in the UK with 29 universities and 74 principal investigators working with 158 research students and postdoctoral researchers. The academic community demonstrated commercial awareness and willingness to collaborate with industry. Further 130 companies, primarily members of the Energy Harvesting Special Interest Group (EH SIG) and the Energy Harvesting Network were mapped onto a supply chain. With healthy numbers in enabling technologies (materials, transducers, electronics etc.) and applications and end users the bottleneck was identified in the area of energy harvesting devices. A clear challenge is in finding applications for energy harvesting which are of sufficient scale to support a viable business when the technology is still rather bespoke for each application. Among the members of energy harvesting components and devices technical capabilities are well balanced and cover materials for transduction and manufacturing, vibration, solar, thermal and other energy harvesting technologies. Analysis of 9 different sectors, which were originally examined in the “Industry Needs Analysis: Potential opportunities for energy harvesting” report published by the EH SIG in May 2013 showed three clear leaders. These are Infrastructure & Structural Monitoring, Aerospace and Industrial Process Control & Monitoring. The report has also identified two strong industrial clusters around the University of Southampton and the University of Cambridge. The academic exper- 4 tise is widely distributed across the UK and in many leading universities. Though we expect progress to be made in this area through collaborative projects funded by the Technology Strategy Board in 2012, more should be done in the future. Bringing design and product development companies into collaborative projects, which wasn’t the case in the previous funding competition, potentially offers an opportunity to bolster innovation and commercialisation in the area of energy harvesting. In addition, more effort to engage system integrators should help the supply chain develop further. Energy Harvesting SWOT Analysis The SWOT analysis highlighted that the strong research base in the UK that has produced a number of excellent advanced energy harvesting technologies has not translated into equally strong businesses. The reasons are numerous: fragmented applications with specific requirements, complex supply chain, disconnection between R&D players on the one side and systems companies and users on the other. Despite these weaknesses and facing a number of threats to its potential to be world leading in energy harvesting, the UK EH community is in a good position to benefit from the opportunities emerging locally and internationally. The EH SIG will continue supporting companies and academics involved in the Energy Harvesting sector and its activities will be outlined in the business plan for 2014-2015. Introduction About This report maps the capabilities relevant to energy harvesting in the UK and identifies the organisations active in energy harvesting research and development as well as commercial exploitation. It serves two specific purposes: 1. A baseline mapping of energy harvesting activity in the UK for the Technology Strategy Board (TSB) to support their tracking of impact of support for the area under the Emerging Technologies Programme 2. A more widely available resource to enable those interested in the exploitation of energy harvesting technologies to find both academic and commercial expertise Energy Harvesting Special Interest Group The report has been compiled by the Energy Harvesting Special Interest Group (EH SIG). The TSB established the EH SIG to help accelerate the development and commercial use of products, processes and services based on energy harvesting technology, through networking the full supply chain and facilitating the emergence of a self-sustaining commercial ecosystem. Further information on the EH SIG can be found at https://connect.innovateuk.org/web/eh1 The EH SIG brings together the community along the value chain – from academia, materials technologies, devices, systems integration and through to the user communities helping build a vibrant and productive Energy Harvesting community in the UK. Approach and scope The report sets out to address the following objectives: • Identify and describe capabilities of UK academic groups • Identify and describe capabilities of technology supply companies in the UK • Identify companies that have used or evaluated energy harvesting • Map community activities related to energy harvesting • Provide analysis of UK strengths, weaknesses, opportunities and threats To do so a variety of sources were consulted including the EH SIG’s own membership, the membership of the EPSRC funded Energy Harvesting Network, attendees at a range of energy harvesting related conferences, events and workshops, successful applicants to the TSB’s ‘Energy Harvesting for Autonomous Sensing’ competition and LinkedIn Energy Harvesting Group. Relevant organisations were questioned to understand capabilities and levels of commercial interaction. Whilst there is good confidence that the majority of academic groups and energy harvesting technology developer companies have been captured it is not possible to provide a comprehensive picture of every potential user company that has evaluated energy harvesting or has otherwise shown significant interest in the technology. For this part of the supply chain our intention is rather to provide a more qualitative view based on the membership of the EH SIG and Energy Harvesting Network. This enables a reasonably clear understanding of which applications sectors have been most actively engaged so far and therefore where there is potential for further support either to focus effort by sector or to help less represented application sectors to understand the potential of the technology to address their challenges. We welcome any input on companies or academic groups that have been actively engaged in energy harvesting work and have not been captured here. Please forward information to alex.efimov@ktn-uk. org. 5 Academic Community Introduction As the very beginning of the supply chain for commercial energy harvesting devices, the academic community is the primary source of knowledge on the development of the technology. The academic base in the UK has been investigated to understand its extent and the degree to which it is enabling commercial exploitation of energy harvesting technologies. Approach and sources In order to be as comprehensive as possible in surveying the UK academic community a range of sources were consulted initially to establish the likely groups active in the field. These included the membership of the Energy Harvesting Network, attendees at a range of European energy harvesting events and research projects involving significant energy harvesting focus. Once these academics had been identified effort was made to identify from them, which were substantially involved in energy harvesting related research as opposed to just having an interest in the technology. These candidates were then contacted for a further level of detail on their activities. Following this the information was consolidated on a per institution basis. Analysis This analysis presents a view of the state of the UK academic energy harvesting community. In particular, it focuses on how large and diverse this community is and the extent to which it interacts with the business community. This level of interaction will be key to the success of any efforts to commercialise the technology in the UK. Research groups with substantial activity in energy harvesting were identified at 29 universities. In a number of these cases there was more that one 6 department involved at the institution and in such cases these were not always collaborating with each other. This is a significant growth in activity since a less rigorous identification of research groups in 2008 found less than 10 institutions engaged in energy harvesting. Energy harvesting related R&D is primarily carried out in various engineering departments (electronic, electrical, mechanical, aerospace). There are also a smaller number of groups in chemistry, computer science, materials sciences and other departments. In terms of research personnel, 74 Principal Investigators (PI’s) were identified. These ranged from some large groups with up to 5 PI’s to many with a single PI. Working for these PI’s are 158 research students and postdoctoral researchers. Again there is very significant variety in research group size ranging from a single student to the largest groups having 10-14 researchers under supervision. The clearest indication of the extent to which academic energy harvesting researchers are facilitating commercial exploitation of the technology is to be found in their interaction with industry. Only 8 of the 28 institutions have not been involved in any industrial collaborative work yet. Companies from across energy harvesting systems and component developers through to potential end users of energy harvesting powered solutions have all engaged in collaborative R&D. This clearly indicates that the majority of academics are interested in commercially relevant R&D and also that the industrial community recognises the need to access the significant expertise in academia in this field. Further positive indication of commercial focus emerging in the academic community is that 12 of the 28 institutions have indicated patenting activity. This includes patents received, applied for or applications currently being prepared. There are many academic conferences covering energy harvesting technologies. These range from technology specific ones through to more general conferences such as PowerMEMs. An important indicator though of how readily the academic community is reaching out to industry is in the extent of presentation at events or workshops where there is a significant industrial audience. This helps to raise awareness of the technology, its capabilities and limitations and also helps industry to identify expertise to help it address industrial applications. It is therefore very encouraging that 16 of the 28 institutions have already presented at such industrially focused events. There is still however scope for further encouragement of the academics to raise awareness or their work. integrating energy harvesting solutions the UK has a significant technical advantage on which to build commercial exploitation. The academic groups are listed in the table below along with a short description of their areas of activity. The groups themselves provided these descriptions. The Principal Investigators are also listed. There is coverage of all major technology areas within the community including vibrational (electromagnetic, piezoelectric and electrostatic and newer techniques such as magnetostrictive), thermoelectric, RF and photovoltaic (including novel 3rd generation PV materials). There is also considerable focus on the electronics and power management and in systems design and modeling. It is worth noting that there is no particular geographical clustering of energy harvesting expertise in the UK. There are very strong groups in all of England, Scotland and Wales. In summary, the academic energy harvesting community in the UK is a real strength. There are a significant and growing number of groups with a high proportion actively engaged in industrially collaborative R&D. Other indicators also support a view that the community has a significant interest in industrial engagement and commercial exploitation. The existence of the Energy Harvesting Network has served to make the community more cohesive. This technical base is something that can be built on with the high interest in energy harvesting showed by the potential user community.

Design, fabrication and use of personal energy generation solutions based on functional materials and devices including thermoelectric, ferroelectric, pyroelectric, piezoelectric and solid oxide fuel cell devices. 2. Design, fabrication and use of environmental and structural health monitoring sensors. 3. Environmentally friendly manufacturing routes, which minimise energy, material and chemical usage, for producing functional materials and devices. The three themes come together in the manufacture and development of self-powered sensor nodes. A total of 364 individual members of the EH SIG, including academics and industrialists, were reviewed and analysed to understand the current status of the EH sector. Other companies were identified through Google search, LinkedIn and network referrals as well as an analysis of UK company members of the Energy Harvesting Network. Though the list is by no means exhaustive, it provides a comprehensive snapshot of the Energy Harvesting sector in the UK. Focussed on two main aspects regarding vibration based energy harvesting – namely nonlinearity and uncertainty. Have done theoretical and experimental works on energy harvesting by exploiting nonlinear vibration phenomenon. Also quantifying harvested energy when there are uncertainties in the input motion and/or systems parameters. - Energy Harvesting Components, which includes materials for transduction and basic electronics and transducers Research covers thin films and sensors. We can make large scale devices on a variety of substrates, including polymer film, using commercial-scale deposition equipment. Currently we are working on piezoelectric films and low cost hetero-junction solar cells. The companies were reviewed and qualified based on the information gathered from their websites or direct contacts. Then they were mapped onto the supply chain diagram, which consists of the following elements: - Energy Harvesting Devices or complete energy harvesters ready for integration into various industrial applications - Energy Harvesting Design and Consultancy companies considered separately. Energy Harvesting Components In total 20 companies were identified as relevant to this category. Johnson Matthey, Morgan Advanced Materials plc and CeramTec UK Ltd make piezo ceramics and therefore clearly fit into this category. A number of other companies such as BASF, Tata Chemicals and other have potential to supply the Energy Harvesting sector. This group includes one company from Japan, one from Cyprus, two companies from the US and one international, because though BASF writes about its interest in EH, it is impossible to determine where this activity is located. In this category we can see a strong cluster of companies that make solar energy harvesting cells: Sharp, G24 Power, Solar Press and Eight19. A number of companies in the table below are foreign companies or large internationals with variable levels of presence in the UK. The location is shown in the table below in brackets. - Industrial Applications and End Users: a category that includes companies, which made a significant progress towards or have reached the market already. Typically a company in the Industrial Applications category would have sold EH products to users or have commercialisation partners. A company from the End Users group is typically an established business with a clear unfulfilled need in energy harvesting. ‘Industrial Applications’ and ‘End Users’ were merged together in this report because the TRL and the level of adoption are often difficult to judge based on the information available in the public domain. In the future updates of this report, when the ‘Industrial Applications” category gains more weight, it will be 14 15 16 Company (Country) Areas of Expertise W.E.

Gas Sensing Solutions Ltd, Solar Press, Seamless Sensing 2. GE Aviation Systems, University of Cambridge 3. Perpetuum Ltd, University of Southampton 4. Elster Metering Limited, Staffordshire University 5. Piezotag Limited, Severn Trent Water, Coventry University 6. Molecular Solar Ltd., University of Warwick 7. Sharp Laboratories Of Europe Ltd, Highland Biosciences Ltd. 8. European Thermodynamics Ltd, University of Glasgow 9. Smart Component Technologies Ltd, Network Rail, Thales, Severn Unival 10. Microsemi, IntelTech, Cardiff University The Metrology for Energy Harvesting This European project is addressing the lack of accurate and standardised measurement that hinders development, innovation and market acceptance of EH devices. It helps to commercialise EH technologies by developing ‘traceable’ (can be traced back to national standards) measurement methods, enabling industry and consumers to directly compare different EH technologies such as thermoelectric and vibrational harvesting devices. The EnOcean Alliance Supply Chain The EnOcean Alliance, according to its website, now totals 172 companies. In 2010, over 50 new member companies joined the consortium, resulting in 50 percent growth over 2009. The group is structured in three tiers: promoters, participants and associates. A number of companies in the are involved in the EnOcean Alliance, most notably MK Electric, which is a part of Honeywell. Energy Harvesting SIG consisted of 364 individual members when the capability mapping exercise commenced. The EH SIG membership is free and open to anyone interested in energy harvesting. This policy led to a diverse community of academics and industry with many members being foreign researchers or companies. In addition to EH SIG membership, 128 UK members of the Energy Harvesting Group on Linkedin were reviewed as well as the UK members of the Energy Harvesting Network. Relevant companies were mapped onto the supply chain: - Energy Harvesting Components: 20 - Energy Harvesting Devices: 7 - Energy Harvesting Design and Consultancy: 23 The Electret Alliance: UK/Japan Consortium - Industrial Applications and End Users: 52 A new collaboration has recently emerged in Japan. The Electret Alliance was established in April 2013 as a partnership between industry and the academic community to promote R&D, as well as to enhance awareness and promote the propagation of the electret vibration generator. In the midst of global enthusiasm for energy harvesting, our electret vibration generator has reached the stage of commercialization. One of the members is a UK company THHINK Wireless Technologies. Other members are: • The University of Tokyo • Omron Corporation • Asahi Glass Co.,Ltd : • Techno Design Co.,Ltd • Konishiyasu Co.,Ltd FP7 A number of collaborative energy harvesting projects involving industry were funded through the Framework Programme 7. UK was mainly represented by universities in the FP7 projects. The project involves metrology organisations from Germany, UK, France, Finland, Slovenia, Italy and Czech Republic. The UK is represented by NPL. 32 33 Academic research was identified at 28 UK universities, where a total of 224 senior researchers, postdocs and PhD students work in the area of energy harvesting. It provides a robust and solid foundation to the UK energy harvesting community. The bottleneck is in the area of commercial activities related to energy harvesting devices. It could be explained by a huge diversity and fragmentation of end-user applications and their power requirements. With no universal solution covering a substantial share of industry sectors, the business of making energy harvesting devices becomes risky. Only a few companies were successful in finding a profitable market niche: a good example would be Perpetuum Ltd, which makes energy harvesters for wireless monitoring of trains. 3. Solar 4. Thermal 5. Other technologies including electronic components and energy harvesting technologies that didn’t fit into other categories All major energy harvesting technologies such as vibration, motion, solar and heat were represented in the sample group of technology providers with vibration energy harvesters using piezo materials and DSSC for harvesting solar energy being the most popular ones. We can also observe a healthy number of collaborations involving researchers and companies from different areas of the supply chain. However, none of the TSB funded projects funded in 2012 included designers of engineering consultancies. Bringing design and product development companies into collaborative projects potentially offers an opportunity to bolster innovation and commercialisation in the area of energy harvesting. Components and Devices The picture looks very balanced: with good numbers in each category. Though the thermal energy harvesting may seem to be lagging behind, it is represented by a very strong company, European Thermodynamics Ltd, that already made significant progress in productionising thermoelectric generators (TEGs). Companies from these two groups demonstrate significant diversity in terms of energy harvesting technologies, which could be best summarised in the following five categories: 1. Materials for transduction and manufacturing 2. Piezo and other vibration energy harvesting technologies 34 35 Industrial Applications: Sector Analysis The investigation of the need in industry for wireless solutions and the exploration of the potential for these to be powered by energy harvesting was carried out by application sector. A set of 9 different sectors originally were examined in the “Industry Needs Analysis: Potential opportunities for energy harvesting” published by the EH SIG in May 2013. These are: Sector Number of Companies Aerospace 12 Agriculture 1 Automotive 3 Building automation 2 Health & Medical 4 Industrial process control & monitoring 11 Infrastructure & structural monitoring 15 Oil & gas 1 Rail 3 The same sectors were applied to the list of companies in the End Users and Industrial Applications category. Three sectors emerged as clear leaders, as shown below: Infrastructure & Structural Monitoring, Aerospace and Industrial Process Control & Monitoring. The Aerospace sector also includes companies, which specialise in defence and security applications, which partly explain the high number. For example Dstl was placed in this category because it is the best fit among all sectors in the list. It is interesting to note that although the building automation sector is the most developed area for commercial energy harvesting this is not strongly represented in 36 the UK. The sector is very strong in Europe, in particular in Germany, and represents an opportunity to build awareness of practical application here in the UK. Energy Harvesting Clusters Two technology clusters were identified in this report. One cluster formed around the University of Southampton. A number of energy harvesting technologies developed at this university were successfully commercialised, which led to formation of a number of companies still geographically based near the university. Geographical proximity to Southampton enables them to continue collaborating with the academics on developing new technologies or improving the existing ones. The Cambridge cluster is slightly bigger but less monolithic and includes companies from all components of the supply chain with some companies having no relation to the University of Cambridge in terms of their origins. 37 EH SIG Community Activities Energy Harvesting Network PowerMEMS 2013 The Energy Harvesting Network is a network of UK academic and industrial researchers and end-users of energy harvesting technologies and was originally funded by EPSRC. Its website states that at January 2014 there were: 03 Dec 2013 • 271 members from 179 academic institutions currently registered with the Energy Harvesting Network Energy Harvesting Mission USA • 136 members from 156 companies currently registered with the Energy Harvesting Network. Activities of the Energy Harvesting Network have been focused on defining new research challenges through roadmapping activities and helping catalyse collaborative research proposals. It also disseminates information about the current and future capabilities of energy harvesting technologies to all potential users in both industry and academia. This dissemination activity, through its annual event, is its primary focus now that EPSRC funding has ended. Cambridge Cluster: Southampton Cluster: University of Cambridge University of Southampton pragmatIC Printing Ltd Ilika Plc Eight19 Ltd Perpetuum Plextek Ltd Synapse Electronics Sentec Ltd Sagentia IDTechEx The 13th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications 20 Nov 2013 UK Energy Harvesting Mission to Japan 16 Jul 2013 Energy Harvesting & Storage Europe 2013 17 Apr 2013 - 18Apr 2013 Energy Harvesting 2013 25 March 2013 The Energy Harvesting Network has a common interest with the EH SIG in dissemination although its focus is primarily on the academic community. The two organisations therefore already work closely to coordinate plans and collaborate on various activities such as energy harvesting themed events for industry and academia. The EH SIG has a much greater focus on the development of the supply chain for energy harvesting recognising the UK academic strenght at the beginning of this. Events The EH SIG organises a number of events to benefit the energy harvesting community . Several examples are listed below: 3rd UK-Japan Energy Harvesting Workshop 06 Dec 2013 TTP Ronsek Innovation 38 39 Energy Harvesting SWOT Analysis 40
