Abstract (en)
[origin: WO2010001019A2] This device (4) allows the detection of the presence of an object in a detection zone by measuring a variation in capacitance brought about by the presence of said object. It comprises an element (6) for emitting an electric field, an element (8) for receiving an electric field, and means for measuring the coupling capacitance between the emission element (6) and the reception element (8), the emission element (6) emitting an electrical signal received by the reception element (8) so that a coupling capacitance of a predetermined value is established between the emission element (6) and the reception element (8) when no object is present in the detection zone, a variation in the coupling capacitance indicating the displacement of an object in the detection zone and the establishment of a capacitance of a different value from the predetermined value indicating the presence of a static object.
