Abstract
A sensor device a sensor unit which detects a biomedical signal, and a transmitter which converts the biomedical signal into a radio signal and then transmits the radio signal. The transmitter has an electrode detachment detection unit 12 which detects electrode detachment on the basis of an output of the sensor unit, and transmits an electrode detachment signal indicative of the detachment. In a receiver, the biomedical signal transmitted from the transmitter is received, the signal is attenuated by an attenuation unit, and the attenuated signal is supplied to a wired sensor input portion of another device through a switch and a connection unit. In the receiver, when the electrode detachment signal is detected from the signal transmitted from the transmitter, the switch is turned off.
