The day to go out for a must-have treasure may be over! Researchers at Michigan State University in the United States have designed a low-energy nanopower generator that converts the force of a person's sliding and pressing the screen into electricity. In the lab, they successfully used this device to drive an LCD touch screen, a set of LED bulbs, and a folding keyboard.
Sepulveda, an assistant professor of electrical and computer engineering who is in charge of the study, published an article in the journal Nano Energy, saying that the device is made of silicon wafers and divided into multiple layers that generate electricity when pressed. It is light weight, collapsible, biocompatible, scalable, and can be used in wireless helmets, cell phones, and other touch screen products.
Sepulveda said that its advent means that human beings have taken a step closer to a wearable device powered by energy. In the near future, you may have to charge your mobile phone once a week because the electrical energy has been added in time as your finger moves. According to Xinhua News Agency
