TELEMETRIC SENSOR FOR CONTROLLING WAKEFULNESS ON ELECTRODERMAL ACTIVITY SIGNALS Russian patent published in 2017 - IPC B60K28/06 G08B21/06 

FIELD: physics.

SUBSTANCE: sensor contains a wrist bracelet for the operator, on the inner surface of which electrodes are fixed for recording the galvanic skin reaction associated with the current source and the microprocessor-based signal processing unit installed in the body that is placed on the outer surface of the bracelet, a radio communication channel with wakefulness facilities. And the electrodes are placed on the opposite surfaces of the bracelet, one of the electrodes is reference, it is partially enclosed by the wrist and is placed on the side of the body with the possibility of abutment to the dorsal surface of the hand and galvanic contact with it, and the other - in the form of a matrix of independent electrodes with the possibility of galvanic contact with the inner surface of the wrist. Independent electrodes are connected via individual current sources and the multiplexer - to a signal processing unit with the possibility of periodically interrogating matrix elements with the allocation of the signal with the greatest amplitude for controlling the wakefulness facilities.

EFFECT: increasing the signal-to-noise ratio.
