Abstract: A pressure-compensation device for a housing includes: an inner side; an outer side; and a lattice-like cage having a gas opening. The gas opening connects the inner side and the outer side in a flow-conducting manner and is restricted, in a through-flow direction of the gas opening, by an inner edge and an outer edge. The gas opening is covered by a gas-permeable membrane. The membrane comprises a nonwoven-fabric composite part and has at least one nonwoven-fabric layer.

Abstract: A sensor element includes: a supporting body; and a sensor body, the sensor body being planar in shape, being made of an elastic material, and having a first surface and a second surface coated so as to be electrically conductive. The sensor body includes a measuring segment and a fastening segment. A layer thickness of the fastening segment is greater than a layer thickness of the measuring segment.
