PiezoElectricity piezoelectric film when coated onto the surface of the device can sense pressure changes each time you enter or touch the screen to energy for recharging the phone, even when you hold machines on hand.

Experts said the technology will soon be launched. Then, the smartphone will never worry about running out of battery. Team of scientists creating the technology also has the ambition to turn the heart of man the tool generates energy.
