A multi-university team of engineers has developed what could be a promising solution for charging smartphone batteries on the go — without the need for an electrical cord.
Incorporated directly into a cell phone housing, the team's nanogenerator could harvest and convert vibration energy from a surface, such as the passenger seat of a moving vehicle, into power for the phone. "We believe this development could be a new solution for creating self-charged personal electronics," saysXudong Wang, an assistant professor of materials science and engineering at the University of Wisconsin-Madison.
