Abstract
A thermoacoustic transducer integrating at least one piezoelectric element having a first surface and a second surface, a potential electrode that is electrically connected to the second surface, a ground electrode that is electrically connected to the first surface, a switch electrically connected to both the potential electrode and the ground electrode, a timer configured to match a pulse emanating from a radio-frequency emitter, further wherein the potential electrode and the ground electrode are electrically connected through an impedance when the switch is in an active state, further wherein the potential electrode and the ground electrode are not electrically connected when the switch is in an inactive state; and a housing accommodating the at least one piezoelectric element, potential electrode, ground electrode, and switch.
