Art of Paper Cutting can change the Future of Electronics!!!!!!!!

Ever wonder why all our gadgets are rigid rectangles? It doesn’t have anything to do with the outside of the device, but the inside. Electronics are full of conductive sheets, which are basically responsible for shooting electricity and data between components. While technically flexible, conductive sheets are designed to be flat, and become less efficient when they bend due to tearing. It’s why our smartphones only gently curve, why our tablets don’t fold, and why our wearables seem underpowered.
But that might all be set to change. A University of Michgan research team lead by Professor Nicholas Kotov has figured out a way to apply Japanese paper cutting techniques, called kirigami
to a new type of flexible conductor, opening the door to gadgets that bend, flex, fold, and transform.
In a paper published in April 2017 in the journal ACS Nano, researchers detailed how the traditional Chinese and Japanese technique of paper-cutting—basically, the art of slicing unique designs in paper—may be the key to the development of "lightweight, superportable, and sustainable power sources" for devices including remote controls, watches, and temperature sensors.

The key is a rhombic paper-cut design just a few inches long. 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 harvester. 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.With enough movement, the new devices could charge in a matter of minutes. Who knew the future of power could be so artistic?
