2 Garments
Within the scope of MOBISERV two different types of garments have been designed and
produced for vital signs monitoring: the first one refers to sensorised shirt and band for day
use, and the second one to pyjama for night use.
After the first prototype of garment (see deliverable D5.2) and following the remarks of the
users, a second generation of garment have been designed taking into account the use of new
technology for the respiration measurement (IPG at the place of strain gauge sensor). In this
document the second prototypes of garments are presented.
2.1
Sensorised shirt and Band
The first trials carried out with the end-users highlighted that the older persons encountered
some difficulties to wear the first version of shirts.
Although older people generally like loose clothes, they were happy to have them fitted at
chest level and moreover they like the vests with straps as they can easily slip into them
without lifting their arms above their head.
To respond to this feedback a second version of shirts for the day monitoring has been
designed to grant easiness of use as a primary goal thanks to a zip fastening that can be totally
opened to facilitate the donning.
Two more electrodes have been added to the shirts and band in order to be able to monitor the
respiration through thoracic impedance measurements thus removing the piezo sensor with
the aim to increase comfort and reduce the overall production costs and time.
However, in the band, the piezo sensor for respiratory movement detection has been
maintained in order to be able to perform comparative tests if needed.
The shirts are made with cotton fabrics which is one of the preferred materials by older
persons.
Both shirts and band presents:




four textile electrodes placed on the chest region to detect ECG (1 Lead) and respiration
through bio impedance measurements
one mini jack connector to plug the electronic
a pocket to house the electronic during use
a Velcro® fastening for the band and a zip for the shirts
Shirts and band are illustrated in Figure 1.

2.2
Pyjama
For the night monitoring a new version of the Pyjama has been designed.
The second prototype of pyjama includes two temperature sensor to address the need to
monitor the skin temperature during the night in order to prevent discomfort problems related
to uncompensated nocturnal heat loss which are quite commons in elderly.
The chosen sensor is a commercial thermistor which gives reliable information with a 0.1
degree of accuracy. Two sensors has been integrated, one in the cuff and one in the hip region
respectively.
The choice of the location is the result of two different goals: the aim to maintain comfort for
the user on one side, and the need to grant a good contact with the skin in order to reach a
thermal equilibrium with the body on the other side.
The chosen regions seem to be the best trade off between reliable information and comfort
for the user.

3 ANT for Wireless Body Array Network
TM
The new multi-sensor system integrates a Wireless Body Array Network (WBAN). This
WBAN enables to add sensors which can be distributed on the body. The technology used is
ANTTM ecosystem. However, the use of the WBAN has some restrictions concerning the wave
propagation around the body.
A wireless temperature sensor has been specifically designed and integrated in the pyjama to
monitor the skin temperature of the subject in two different sites.

The measured A/D data represents the voltage drop across the thermistor.
In order to calculate the corresponding resistance value the following conversion must be
applied to the data value:
Once the resistance value is calculated, the Steinhart-Hart equation can be used to estimate
the corresponding value of temperature (Kelvin degrees):
where A = -6.151082E-3, B = 1.2127443E-3 and C = -2.8552001E-6

4 Data logger
4.1
Hardware description
The first version of the MOBISERV data logger has been updated with the integration of a
ANT module used for the wireless body array network. In the first version, the respiration
sensor was a strain gauge, in this second version, there is the possibility to use either a strain
gauge or the impedance plethysmography measurement. CSEM has redesigned the user
interface by adding 4 LED. The jack connector is now integrated into the housing in order to
increase the ergonomic. The embedded signal processing has been improved. In this second
version, the fall detector is not yet implemented. The next version of software will offer this
feature. This second version of MOBISERV data logger provides the following features:
 one 4-pin jack connector for textile sensors (ECG and IPG or strain gauge),
 one USB connector for configuration and data transfer,
 one micro-SD memory card slot,
 four status light,
 one mode switch,
 one reset switch accessible through a hole.

Introduction
This section details step by step the installation of the whole software package developed for
the Mobiserv project. The second part concerns the use of the Graphical User Interface, that
means:


real time monitoring (streaming mode),
daily monitoring (recording mode).
Both modes can be used simultaneously.
The software package used for the Mobiserv project is split into two main parts:


a daemon running in background which is in charge of downloading new sessions to
the PC,
a viewer which is providing the user the ability to make operations such as streaming,
recording and viewing online signals (streams) and offline signals (sessions).
The diagram below describes the main architecture of the two parts of the software package
and how they interact with the hardware.

Downloader
USB driver uses with the data logger has to be installed before doing anything else. The
downloader tool can be downloaded from the following link:

http://csnej106.csem.ch/sec251/sewOS/#host_software
Currently, only the Windows7 version is available. The downloader application runs in
background and downloads new sessions without any action from the user. Double clicking
on MobiservDownloader.jar will start it.
Figure 12: Starting Mobiserv Downloader
It is strongly recommended to make a shortcut to this jar file in a more convenient
location to launch it.
The launch of the MobiservDownloader application provides this message.
Figure 13: Message telling a successful start of the downloader
Once the data logger is connected via USB, all new sessions in the SD memory card are
downloaded in the sessions folder without any notification. The idea is to keep this program
running in the silent mode.
6.5
Viewer
The new viewer, developed for Mobiserv is a graphical user interface that plots the sessions
and the streamed data on a PC display. It enables acting the data logger online. The user can
connect / disconnect the data logger, start and stop the streaming and the recording. Of

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the MOBISERV data logger is used exceeds the applicable RF compliance level above, the
MOBISERV data logger should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the MOBISERV
data logger.
Recommended separation distances
The MOBISERV data logger is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the MOBISERV data
logger can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
MOBISERV data logger as recommended below, according to the maximum output power of
the communications equipment

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.

Maintenance and care
The sensorised garments are realised using natural and synthetic yarns and must be treated as
an underwear. Garments have been tested for their endurance regarding number of washings
and time of use. The garment starts to show some malfunctioning after about 50 delicate
washing cycles, probably due to the attack of detergents to metallic fibres; at the same time
the fabric start to wear away.

Washing must be done by hand (no washing machine) in cold water, avoiding to put
the connector in the water.
The garment must be washed with a delicate soap (e.g. shampoo) without using
softeners.
Wash separately.
Do not use bleach.
Do not tumble dry.
Do not iron.
Do not pull cables coming out of the vest.
Do not unplug the connector from the MOBISERV data logger pulling the cables.
the MOBISERV Data logger must be removed from the garment before washing.
