US Patent 7936112 - Piezoelectric nanowire transducer

This patent from Samsung includes some broad claims to an electrical energy generator based on piezoelectric nanowires which may be useful to remote powering of MEMS devices. Claim 1 reads:

1. An energy converting apparatus comprising:

first and second electrodes spaced apart from each other; and

a first nanowire formed on the first electrode, which is composed of a piezoelectric material, the first nanowire being configured to resonate in response to an electromagnetic wave at a first frequency so as to contact the second electrode.
