Abstract

For a simplified construction of a hearing aid device with respect to switch, control and regulating elements, one or more pressure or pressure and position sensors, which are constructed in a film-like structure to react with variable resistance, are composed of laminated polymer layers wherein one layer is coated with interdigital electrodes and the appertaining other layer is coated with semiconductor material. The sensor elements are arranged on either the outside or inside of the housing or can be arranged on a structural member, such as a carrier situated within the housing. The sensor or sensor elements, respectively, can be fashioned as part of the switches or as regulators for the operation of the device.
