Electromechanical transducer for converting mechanical input variable into electrical resistivity in man-machine interface, has resistance element fixed at outer geometry and base, where input variable is changed in elongation of element
The transducer (1) has a base (5) to which an outer geometry (3) is relatively movably supported in a degree of freedom. A polymer-based strain-sensitive, elastically stretchable electrical resistance element (17) is mechanically fixed at the outer geometry and the base. A mechanical input variable is changed in an elongation of the resistance element by generating electrical resistivity. The resistance element is applied on substrate layers, and extended from a disk shaped middle contact element (21) to a radial satellite contact element (19) that lies outside middle attachment.
