Patent ID: 7382205

Claim:
An electromechanical transducer for transducing an electrical input signal into an electrical output signal, the transducer comprising: a substrate, an electrically conductive resonator element attached to the substrate, the resonator element extending in a longitudinal direction having a length, the resonator element including a deformation-free part, a first part that extends a first length from one side of the deformation-free part in the longitudinal direction, and a second part that extends a second length from the other side of the deformation-free part in the longitudinal direction, the resonator element being attached to the substrate only in the deformation-free part, and an electrically conductive actuator able to receive an electrical actuation potential difference with respect to the resonator element for inducing an elastic deformation of the resonator element, the actuation potential difference being a function of the input signal, the elastic deformation comprising a change of the length, the resonator element comprising a resistor with an ohmic resistance which is a function of the change of the length, the output signal being a function of the resistance.
