The portable electronic devices with high features and vast advanced technologies are used by the people around the world. But one of the thing is the electronic devices need power to use it and it is an major source for the functioning of device.

So people always find plug sockets to charge there devices. The researchers have prepared a reporting in the journal ACS Nano, have developed a light-weight, paper-based device arts of paper-cutting that can store energy from body movements.

Portable electronic devices, such as watches, hearing aids and heart monitors, often require only a little energy. They usually get that power from rechargeable batteries. But Zhong Lin Wang, Chenguo Hu and colleagues wanted to see if they could find our small energy needs from the wall socket energy or from a user's body movements.

Wang and others have been working on this approach in recent years, creating triboelectric nanogenerators (TENGs) that can store and drive the mechanical energy all around us, such as that created by our footsteps, and then use it to power portable electronics. But most TENG devices take several hours to charge small electronics, such as a sensor, and they're made of acrylic, which is heavy.

So the researchers turned to an ultra-light, rhombic paper-cut design a few inches long and covered it with different materials to turn it into a power unit. The four outer sides, made of gold- and graphite-coated sand paper, comprised the device's energy-storing supercapacitor element.

The inner surfaces, made of paper and coated in gold and a fluorinated ethylene propylene film, comprised the TENG energy that consumes human energy. Pressing and releasing it over just a few minutes charged the device to 1 volt, which was enough to power a remote control, temperature sensor or a watch.
