Abstract
An energy harvesting device capable of harvesting multiple forms of energy. The device includes a base, a piezoelectric cantilever, and a carbon nanotube film. The piezoelectric cantilever includes a piezoelectric layer disposed between a top electrode and a bottom electrode. A proximate end of the piezoelectric cantilever is supported by the base. The base does not support a distal end of the piezoelectric cantilever. The piezoelectric cantilever is capable of converting vibration energy into electrical power. The carbon nanotube film is capable of absorbing electromagnetic radiation and thermal radiation, and thereafter transmitting heat to the piezoelectric layer. The piezoelectric layer is mechanically deformed in response to said heating, thereby generating electrical power.
