Can Chatting on Your Cell Phone Cause It to Recharge? Researcher Says Yes

Chemical engineering professor, Tahir Cagin is using piezoelectrics, a material made of either crystals or ceramics, to generate electricity. Piezoelectrics were used in World War I in sonar devices. Today, they’re found in microphones, inkjet printers, and even cigarette lighters. The Defense Advanced Research Projects Agency is making a shoe with piezoelectrics that can change the energy created by walking into electric power for charging soldiers’ equipment. Some European clubs even use them to transform the dance power from late night partiers into power to light up the club.

Cagin discovered that when piezoelectrics are small and thin (between 20 and 23 nanometers to be exact), twice the amount of energy is created. By finding the ideal length, he was able to convert the mechanical energy it creates into electric power.

Before the material appears in a cell phone, researchers will have to get a better grip on how to use it on the nano scale. After all, when materials are small, they can do some pretty weird things.
