Abstract
The invention concerns a hearing aid system that comprises an ear canal member comprising a sensor arrangement. The sensor arrangement comprises at least one surface electrode located at a surface of said ear canal member to allow said at least one surface electrode to contact the skin of a user when said ear canal member is operationally mounted on the user. The at least one surface electrode () is adapted to pick up a low voltage electric signal from the user's skin. The sensor arrangement further comprises a light sensor () located at a surface of said housing to allow emitting light through skin proximate to the light sensor () and capturing reflected and/or scattered light when said ear canal member is operationally mounted on the user. The hearing aid system further comprises a sensor signal processing unit () that is connected to the surface electrode () and the light sensor () and that is configured to generate one or more sensor signals from each respective output signal of the at least one surface electrode () and the light sensor (). The hearing aid system further comprises or is connected to an evaluation unit () that is configured to generate an electrocardiogram-representing signal (ECG) from low voltage electric signals picked-up by the at least one surface electrode () and a plethysmographic-curve-representing signal from an output signal of the light sensor ().
