Scientists in the US developed the device, known as a “rectenna”, from a semiconductor just a few atoms thick. Wi-fi signals captured by an integrated antenna are transformed into a DC current suitable for electronic circuits. The device could be used to provide battery-less power for smartphones, laptops, medical devices and wearable technology, according to the US-led team. Because of its flexibility, it could also be fabricated to cover large areas. This has major implications for the future of “electronic intelligence”, say the scientists. Professor Tomas Palacios, director of the Massachusetts Institute of Technology and Microsystems Technology Laboratories Centre for Graphene Devices and 2D Systems, said: “What if we could develop electronic systems that we wrap around a bridge or cover an entire highway, or the walls of our office and bring electronic intelligence to everything around us? How do you provide energy for those electronics? “We have come up with a new way to power the electronics systems of the future – by… Read full this story
