Abstract:
A capacitive sensor with a first electrode and a second electrode, which are spaced apart from one another and which form a measurement capacitance, such that the first electrode is situated on a first substrate body and the second electrode on a second substrate body, and the second substrate body is designed as a deformable membrane in the vicinity of the second electrode, characterized in that a magnetic body is disposed in the vicinity of the second electrode and the membrane, which magnetic body is connected to the membrane and to the second electrode in such a way that a change of position of the magnetic body, induced by an external magnetic field, will cause a change of position of the second electode via the membrane, resulting in a capacitance change, wherein sand capacitive sensor further comprises an electronic arrangement situated in the first substrate body below the first electrode affixed thereon for processing the measurements signals.
