Created by a research team at Louisiana Tech University, the CNF-PZT Cantilever is a breakthrough energy harvesting device, which utilizes waste heat energy from electronic gadgets to power them. The device features the use of a carbon nanotube on a cantilever base of piezoelectric materials. 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.
