Disclosed is a pressure sensor comprising sensor layers ( 12, 14 ) which are made of an elastic, resistive material and are applied to a polymer film that is not represented. ( 22 ) embodies a spacer that is coated with an adhesive. One sensor layer ( 14 ) is provided with a microstructured surface encompassing spherical structures ( 20 ) within an active zone ( 16 ). The compression path amounts to 10 micrometers at an extension R of the structures of 50 micrometers. The structures ( 20 ) are large compared with a certain surface roughness. The inventive pressure sensor is produced by injection molding, etching, embossing, or by means of an electron beam technique or laser beam technique. Disclosed are variations thereof, which function differently.
