Dr. Long Que, assistant professor of electrical engineering at Louisiana Tech University has developed a device called CNF-PZT Cantilever that produces energy continuously without drawing power from any external source. Made from piezoelectric material and coated with carbon nano-tubes to absorb light or heat the device generates power for as long as it’s exposed to thermal radiation.
Capable of self reciprocation the cantilever generate enough power to operate some low-power micro and nano devices, such as biomedical devices or remotely located sensors and communication nodes.
