Charge your cell phones as you walk

Researchers at the School of Materials Science and Engineering at the Georgia Institute of Technology have demonstrated a nano-scale generating that could provide electricity to microscopic machines by harvesting different types of energy from their environment. According to Zhong Lin Wang, professor at Georgia Tech, the generator can convert mechanical energy (such as body movement, muscle stretching), vibration energy (such as acoustic/ultrasonic wave), and hydraulic energy (such as body fluid and blood flow) into electric energy that will be used to power nanodevices without using a battery. “This is a major step toward a portable, adaptable and cost-effective technology for powering nanoscale devices,” said Zhong Lin Wang, Regents’ Professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. “There has been a lot of interest in making nanodevices, but we have tended not to think about how to power them. Our nanogenerator allows us to harvest or recycle energy from many sources to power these devices.” Since a little force due to the body movement is enough to generate continious Direct current the nanogenerators can be used to power up the cell phones or any other portable devices.
