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.
An assistant professor of electrical and computer engineering, Nelson Sepulveda, 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.
Its introduction means that humans have taken a step closer to the wearable device powered by action. (Jing Jing)
