Skin contact sensing device

A skin contact sensing device (10) comprising:

• a contact sensor (11) operable to generate electrical contact signals being indicative of a skin contact;
• a processor (12) connected to the contact sensor (11) and operable to process the electrical contact signals received from the contact sensor (11);
• and
• a memory (15) connected to the processor (12) and operable to store at least one calibration parameter,
• wherein the processor (12) is operable to ascertain a skin contact by processing of the electrical contact signals on the basis of the at least one calibration parameter and
• wherein the processor (12) is operable to read and to obtain the at least one calibration parameter from the memory (15),
• wherein the sensing device further comprises a sensor controller (13) connected to the contact sensor (11) and controllable by the processor (12), wherein the processor (12) is operable to switch off and on the sensor controller (13), wherein the sensor controller (13) is operable to conduct an auto-calibration procedure in response to being switched on and to generate the at least one calibration parameter by conducting the auto-calibration procedure, wherein the skin contact sensing device (10) is switchable into a sensing mode, in which the processor (12) is operable to disregard the at least one calibration parameter provided by the sensor controller (13) in response of being switched on and to substitute the at least one calibration parameter provided by the sensor controller (13) by the at least one calibration parameter stored in the memory (15).
