Abstract
A hearing device has a housing and a first electrode arranged to abut the skin of the individual. The hearing device further comprises at least two different elements selected from the group comprising: a brain-wave measurement circuit receiving measurement signals from the first electrode and from a second electrode arranged to abut the skin of the individual; a communication circuit receiving communication signals from and/or transmitting communication signals to the first electrode; a touch-sensing circuit transmitting sensing signals to the first electrode; a thermoelectric generator thermally connected to the outer surface of the housing mainly through the first electrode; and a charge control circuit sinking a charging current in dependence on a voltage across the first electrode and a third electrode.
