Flat compressible volume capacitive sensor for measuring pressure and/or for the measurement or detection of deformations

The sensor has a planar elastomer film (6) that is formed between electrodes for measuring electric capacitance. The elastomer film is arranged above or below in flexible or rigid surface. A cavity (5) is formed between elastomer film and flexible or rigid surface in an unstressed state of main portion. The outer surface side of main portion is deformed, such that distance between electrodes is reduced by reducing the volume of the cavity to increase measuring of electric capacitance. An independent claim is included for a receptacle.
