Patent ID: 7999446

Claim:
A piezoelectronic device, which comprises: a plurality of carbon nanotubes; at least one piezoceramic layer covering the plurality of carbon nanotubes; and a supporting material for supporting the carbon nanotubes covered with the at least one piezoceramic layer, wherein the supporting material is disposed between the carbon nanotubes, and the piezoceramic layer has a thickness of 0.5 Å to 200.0 Å, wherein the plurality of carbon nanotubes is arranged in a comb-shape; some of the carbon nanotubes electrically connect with each other through the at least one piezoceramic layer; the carbon nanotubes, the at least one piezoceramic layer, and the supporting material together form a piezoelectronic block, and the induced current obtained by the piezoelectronic device is 1.5 μA or above when the size of the piezoelectronic device is 2.5 mm in length, 1 mm in width, and 1 mm in height.
