Abstract
Disclosed is a device for detecting a user's intention to lock or unlock a motor vehicle opening element, the device being intended to be integrated into a handle or into a frame of the opening element and including a voltage source, a printed circuit and at least one sensor for detecting an approach and/or contact of a hand of the user on the handle or the frame. A detection unit of the detection sensor is at least partially in the form of a metallized layer borne by part of an outer contour of a foam block in contact against the housing through a bearing face, the face of the foam block opposite the bearing face bearing the majority of the metallized layer.
