DEVICE FOR MEASURING ELECTRIC SKIN CONDUCTIVITY Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has transducer for converting reference conductivity and conductivity to be measured into pulse sequence which relative pulse duration is proportional to measured conductivity. Protection against pulsating voltage reaching measuring electrodes is one of features included into the designed circuit. The device also has optoelectronic unit and power supply source as voltage inverter of sequential computer port with primary and secondary windings on separate magnetic circuits connected to each other with short-circuited coil. EFFECT: reduced noise influence; enhanced accuracy of measurements. 3 cl, 1 dwg
