Mission
The Laboratory of Sensors and Biosignals (BioSens Lab) is a laboratory dedicated to the design of wearable sensors and the processing of biophysical signals, with particular focus on the stress measurement on drivers. In this facility PhD and undergraduate students can design and test circuits prototypes for biosignals acquisition and also investigate artificial intelligence (AI) algorithms to detect mental stress on humans.
The design activity is supported by electronic CAD software and firmware IDEs to develop new sensors; the AI algorithms can be tested on subjects using a driving simulator available in the laboratory.
In particular, the simulator equipment is composed by a 3 degrees of freedom (3DOF) moving platform, a VR headset, a 65’’ (curved screen) display, a projector with curved screen (82’’) and two professional software simulators able to simulate different traffic conditions and also different car settings in an immersive environment. Moreover, motion cueing of the platform can be customized.
The sensors design aims at acquiring, simultaneously, electrocardiogram (ECG), Electrodermal Activity (EDA) and eye-tracking system (pupil diameter, blink frequency…) of the subject under test.
Equipment
- The laboratory equipment for development and circuit testing consist of 300 MHz oscilloscopes with built-in waveform generators, two triple-output power supplies, two soldering stations, one LCR meter, multimeters
