Classification: CPC A  G | IPC A  G

Claim 0:
1. A device for measuring biological information, the device comprising:
a sensor array formed on a substrate and comprising a plurality of sensors forming an island network in which nodes and a plurality of multi-channels are connected, wherein each of the plurality of sensors comprises terminals for measuring resistance values with respect to tissue activities and functions of skin tissues;
an average value measurement part configured to measure an average value of biological information detected by the sensor array based on the resistance values measured by the terminals;
a communication module configured to transmit the measured average value to the outside;
a controller configured to control the average value measurement part to measure an average value of the biological information based on resistance values measured by at least one of the plurality of sensors in response to a control command received from the communication module; and
a power supply for supplying driving power,
wherein when a resistance value measured by the sensor array changes by a predetermined value or more, the controller is configured to apply additional current to the plurality of sensors so that the plurality of sensors perform calibration for minimizing offset voltage.
