The transducer ( 1 ) comprises an electrically conductive resonator element ( 20 ) extending in a longitudinal direction having a length (l). It can be elastically deformed by an electrically conductive actuator ( 30 ) such that the elastic deformation comprises a change of the length (dl). The resonator element ( 20 ) is electrically connected to a first contact area ( 25 ) and a second contact area ( 26 ) thereby constituting a circuit In this circuit the resonator element ( 20 ) constitutes a resistor with an ohmic resistance (R) which is a function of the length (l+dl). The transducer ( 1 ) further comprises a measurement point ( 28 ) electrically connected to the circuit for providing an electrical signal which is a function of the resistance (R).
