Claim Text:
1. A device for conveying energy through a barrier defining an enclosure without penetrating the barrier, said device comprising: a transducer for selectively converting electrical energy into vibrational mechanical energy at a plurality of discrete frequencies ω a plurality of harvesters for harvesting said vibrational mechanical energy into electrical energy, each of said harvesters in direct contact with said barrier and operating at a respective said discrete frequency ω said plurality of harvesters being oriented so that at least one of said plurality of harvesters is within said enclosure and at least one other of said plurality of harvesters is outside of said enclosure; a control connected to said transducer, said control causing said transducer to operate at a discrete said frequency ω one of said harvesters being adapted to operate at a matching frequency ω from the same said transducer.
