Abstract
A sensor device for potential and/or impedance measurements on a body of a user, including a central electronic unit and at least a first sensor and a second sensor. Each sensor is connected to the central electronic unit by a one-wire connector. Each sensor includes a current electrode and a potential electrode destined to be in contact with a surface of the body. The master includes a master current source configured to circulate a master current in the one-wire connector, the current electrode of the at least first and second sensors and the body, when the sensors are in contact with a surface of the body. Each sensor includes a harvesting device configured to harvest energy from the circulating master current in a powering frequency band.
