Abstract:
1. A film fabrication of a rubber material with piezoelectric characteristics at least comprising: a first electrode layer, having a lower surface; a first PDMS (polydimethylsiloxane) solid layer, having an upper surface and a lower surface, the upper surface of the first PDMS solid layer being corresponding to the lower surface of the first electrode layer; a first PDMS void layer, having an upper surface and a lower surface, the upper surface of the first PDMS void layer being corresponding to the lower surface of the first PDMS solid layer; a bottom PDMS solid layer, having an upper surface and a lower surface, the upper surface of the bottom PDMS solid layer being corresponding to the lower surface of the second PDMS void layer; and a second electrode layer, having an upper surface, the upper surface of the second electrode layer being corresponding to the lower surface of the bottom PDMS solid layer.
