Microcontrollers in embedded
biomedical Applications
Microcontrollers in embedded biomedical Applications:
We want to have systems that :
● are reliable
● are small and lightweight
● have a low power consumption
These issues are critical when we deal with body implants
I: Introduction – Microcontrollers
Some features / advantages of microcontrollers:
●
●
●
●
●
they are small and flexible
easy to use ( most of the time .. )
few external components and wires needed
low and ultra low power designs possible (-> PSoC, ASIC )
wide range of different uCs available
(memory, I/O, speed, busses, A/Ds )
● data interchange using standard bus systems;
-> various peripheral hardware accessible
● IDEs and toolchains for firmware programming /
●
Simulation and high level languages
-> 90% of the manufactured CPUs are not found in desktop PCs but in
embedded systems, with growing areas of application: RFID, hidden
"ubiquitous" computing, wearables, "smart environments", MEMS (micro
electro-mechanical systems)
I: Introduction – Microcontrollers
Some examples for uC-based biomed devices / applications:
● various sensors or meters:
Body temperature, Blood Pressure,
Blood Sugar Level, …
● Implants and prostetics
● Pacer makers (for heart, breathing, ...)
Adam blood glucose meter
● functional Electrostimulation
● Orthesis and artificial limbs
● Biosignal acquisition equipment

I: Introduction – Microcontrollers
Some examples for uC-based biomed devices / applications:
● portable emergency equipment (defibrillator,
..)
● Sports medicine
● Patient monitoring
● “Smart Homes", service robotics
● support of Communication for disabled persons
● wireless sensor networks / Body Area Network (BAN)
● Sensors and Actuators for stationary medical equipment

Pace Makers and Functional Electro-Stimulation
http://www.hgcardio.com/HRhythm/Treatments/a_pacemaker_schematic.jpg
● current pacemakers have 5-7 yrs. battery lifetime
● feedback loops -> adapt to physical needs
● multichannel stimulation and measurement electrodes
Parkinson relief from deep brain stimulation
http://www.firstscience.com/SITE/IMAGES/ARTICLES/dbs/man_pacemaker.jpg
http://www.parkinson-club-u40.de/Hirnschrittmacher.htm
● lack of dopanine in substantia nigra
● hyper-activity of nerve cells
● pacemaker „inactivates“ those cells
Other Areas for FES - Implants / Pacer Makers

Some examples:
● muscle activation / support
● gastrointestinal support
● breathing support
● chronic pain relief
