BIOLOGICAL INFORMATION MEASUREMENT APPARATUS

Abstract:

A biological information measurement apparatus according to an embodiment of the present disclosure includes one or a plurality of measurement channels to be brought into contact with a biological body, and a reference channel to be brought into contact with the biological body. The biological information measurement apparatus further includes a differential circuit that generates a biological signal corresponding to a difference between a measurement signal obtained from the measurement channel and a reference signal obtained from the reference channel, and a switch mechanism that switches contact impedance between the biological body and each of the measurement channel and the reference channel.
