摘要:
A sensor device includes a plurality of electrode chambers, a measurement chamber, and an accommodation chamber which are connected in annular relationship permitting expansion and contraction. Each of the plurality of electrode chambers has a measurement electrode. The measurement chamber has a biological potential measurement circuit which is connected with each measurement electrode via electrically conductive wiring for measuring biological potential of the user by using the measurement electrode. The accommodation chamber has an internal protrusion. The wiring which connects at least one measurement electrode and the biological potential measurement circuit is provided around the protrusion, the wiring having a length which enables longitudinal feeding in accordance with an amount of elongation when the sensor device is elongated. A maximum clearance S between the accommodation chamber and an adjacent chamber is greater than a maximum clearance R between any two adjacent chambers.
