Cell Phones That Never Need To Be Charged?


Utilizing materials known in scientific circles as "piezoelectrics," Cagin, whose research focuses on nanotechnology, has made a significant discovery in the area of power harvesting – a field that aims to develop self-powered devices that do not require replaceable power supplies, such as batteries.

Specifically, Cagin and his partners from the University of Houston have found that a certain type of piezoelectric material can covert energy at a 100 percent increase when manufactured at a very small size – in this case, around 21 nanometers in thickness.


This has ramifications far beyond just cell phones. This could be the new wave of green energy through precisely engineered piezoelectrics. Just think of any place where mechanical stress can be harvested!
