Abstract
The invention relates to a sensor system and several method for the capacitive measurement of electromagnetic signals having a biological origin. Such a sensor system comprises a capacitive electrode device (), an electrode shielding element () which surrounds the electrode device () at least in part in order to shield the same () from interfering external electromagnetic fields, and a signal processing device () for processing electromagnetic signals that can be detected by means of the electrode device (). According to the invention, additional shielding means () three-dimensionally surround the electrode device () and the electrode shielding element () at least in part in order to block out interfering external electromagnetic fields. The changes in the electrode capacity of the capacitive sensor system are determined with the aid of several methods which particularly use the inventive sensor system in order to take said changes into account when the test signals are evaluated.
