Sensor system and methods for the capacitive measurement of electromagnetic signals having a biological origin

A method for minimizing the influence of movement artefacts to measure electromagnetic signals having a biobiological origin, comprising the following steps:

• fitting a sensor system or a measuring device on a measurement object,
• coupling an electrical alternating signal into the measurement object,
• evaluating the coupled in alternating signal in order to determine the electrode capacitance of the electrode device of the sensor system, or the electrode capacitance of the electrode devices of the measuring device, and
• taking account of the determined electrode capacitance of the electrode devices when evaluating the measurement signals of the sensor system or of the measuring device, wherein the relative temporal change in the electrode capacitance of the electrode device of the sensor system or of the measuring device is taken into account, a movement signal of the electrode device relative to the measurement object is derived from the relative temporal change in the electrode capacitance, and the interfering movement artefacts superposed on the electromagnetic signals having a biobiological origin are compensated by means of the determined movement signal.
