Patent ID: 8515532

Claim:
A system for providing motion compensated capacitive measurement of electrophysiological signals, the system comprising: a sensor probe comprising a first capacitive plate and a second capacitive plate arranged to be placed in a proximity of a skin of a human or animal body, wherein a first capacitance between the first capacitive plate and the skin is different from a second capacitance between the second capacitive plate and the skin, and wherein the first capacitive plate is connected to an input of a first amplifier for providing a first measurement signal and the second capacitive plate is connected to an input of a second amplifier for providing a second measurement signal as a measure of an electrophysiological signal of the human or animal body; and a processor connected to the sensor probe and configured for performing the acts of: receiving said first and second measurement signals from the first and second capacitive plates; determining a motion modulated signal from at least one signal of the first measurement signal and the second measurement signal; and providing a motion compensated output signal from the motion modulated signal and the at least one signal.
