1. A piezoelectric isolating transformer characterized by an operating frequency range, the piezoelectric isolating transformer comprising a resonant structure having at least one mechanical resonance in the operating frequency range, said resonant structure comprising:

  • an insulating substrate having a first major surface and a second major surface opposite said first major surface; and

    a first electro-acoustic transducer and a second electro-acoustic transducer mechanically coupled to said first major surface and said second major surface, respectively, of said substrate, one of said electro-acoustic transducers operable to convert an input electrical power in said operating frequency range to acoustic energy that excites mechanical vibration in said resonant structure, the other of said electro-acoustic transducers converting said mechanical vibration to output electrical power.
