Introduction (1/2)
Main objectives of the project :
To develop a generic medical monitoring
system based on a wearable comfortable
garment, integrating smart biosensors
For the prototypes, 2 applications representative
of most markets:
- clinical drug trials
- medical academic research

The biosensors
A wide range of sensors may be integrated
For the 2 first applications:
- ECG (dry electrodes)
- respiratory Inductance Plethismography (RIP)
- skin temperature
- posture/activity (accelerometers)

Data processing (2/2)
Data are stored in a PDA connected to the
garment, with a short range transceiver
Data transferred via RF link are processed and
displayed on a PC platform
