<p>The wearable device comprises a plurality of sensors, a microprocessor, a wireless communication module and a miniature power supply. The plurality of sensors comprises a galvanic skin response (GSR) sensor and a pulse sensor. The galvanic skin response (GSR) sensor comprises a resistance measurement circuit, a low pass RC filter, a pair of electrodes and a conductive gel. The resistance measurement circuit is a Wheatstone bridge circuit with the three arms of known resistance and a fourth arm is kept open. The pair of electrodes with skin contact acts as resistor in the fourth arm. The pulse sensor comprises a pair of light emitting diodes and a pair of light collecting sensors. The plurality of sensors is connected to the microprocessor. The wireless communication module receives data from the microprocessor, encodes it and transmits it to a remote computing device.</p> |
