Ultralight paper device can be charged with body movements
Inspired by the Chinese and Japanese arts of paper-cutting, scientists have developed a light-weight, paper-based device that can harvest energy from body movements to power sensors and watches.
Washington: Inspired by the Chinese and Japanese arts of paper-cutting, scientists have developed a light-weight, paper-based device that can harvest energy from body movements to power sensors and watches.
Despite the many advances in portable electronic devices, one thing remains constant - the need to plug them into a wall socket to recharge. Portable electronic devices, such as watches, hearing aids and heart monitors, often require only a little energy.
They usually get that power from conventional rechargeable batteries. Researchers from Georgia Institute of Technology in the US and Chongqing University in China wanted to see if they could untether small energy needs from the wall socket by harvesting energy from a user's body movements.
