The day of charging cell phones with finger swipes and powering Bluetooth headsets simply by walking is now much closer. Researchers have created a new way to harvest energy from human motion, using a film like device that actually can be folded to more power. With the low cost device known as a nanogenerator. Electrical energy is created when the device is compressed by human motion or mechanical energy. A promising and alternative method for many autonomous electronics such as wireless headsets, cell phones and other touch screen devices.
