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

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