Vibration Energy the Secret to Self-Powered Electronics

Read the full story from the University of Wisconsin-Madison.

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,” says Xudong Wang, an assistant professor of materials science and engineering at the University of Wisconsin-Madison.

Wang, his Ph.D. student Yanchao Mao and collaborators from Sun Yat-sen University in China, and the University of Minnesota Duluth described their device, a mesoporous piezoelectric nanogenerator, in the January 27, 2014, issue of the journal Advanced Energy Materials.
