Patent ID: 8415859

Claim:
A piezoelectric nanodevice comprising: a first planar substrate having formed thereon a multiple number of nanorods; a second planar substrate having formed thereon a multiple number of piezoelectric nanorods; a first plate associated with the first substrate; and a second plate associated with the second substrate, wherein the first plate is moveable in a plane relative to the second plate such that the first substrate associates with the second substrate to generate friction between the nanorods of the first substrate and the piezoelectric nanorods of the second substrate to generate electric voltage, wherein one of: the first plate is coupled to at least one connecting member and the at least one connecting member is expandable by heating and contractable by cooling to cause the relative movement between the first plate and the second plate; or the first plate is coupled to at least one elastic member and the first plate is moved responsive to vibration applied to the first plate.
