| As
remarked before, the equivalent
circuit of a PZT actuator is a capacitor in parallel with
a current generator driven by deformation. Therefore,
once PZT actuators are integrated in the analog circuit,
a source term appers in the governing equation. For instance
in the case of the telegraphist equation we have the following
circuital scheme: |

In
a similar way, because of the PZT transducer, the mechanical
equations exhibit a sorce term driven by the voltage
drop. In the figure the case of a beam in torsion is
shown.
