Operating device for electric appliance, has operating element and operating panel with operating panel-front side and operating panel-rear side, where piezo-sensor element is arranged on operating panel-rear side

摘要

The operating device (10) has an operating element and an operating panel with an operating panel-front side and an operating panel-rear side. A piezo-sensor element (13) is arranged on the operating panel-rear side as a part of the operating element and has a piezo-active layer (14) and an electrode structure (17). The electrode structure consists of electrically conductive carbon. The electrode structure is formed by a layer containing carbon nanotubes. An independent claim is included for a method for manufacturing an operating device for an electric appliance.
