Eco Factor: Device harvests waste heat energy from electronic gadgets.
Researchers at Louisiana Tech University have successfully fabricated a breakthrough energy harvesting device, which utilizes waste heat energy from electronic gadgets to power them. Dubbed the CNF-PZT Cantilever, the device consists of a carbon nanotube on a cantilever base of piezoelectric material.
The carbon nanotube film absorbs heat and forces the piezoelectric cantilever to bend, which then generates an electric current in the material. The device is so small that thousands of small CNF-PZT Cantilever devices can be designed into devices, allowing them to harvest their own wasted energy.
