Sensors, controllers, and other electronic devices embedded in clothing could change the way we interact with computers and with each other. But efforts to turn t-shirts into electronic devices have been hampered by the need to power them with bulky batteries and process their data using stiff circuit boards.
Research published today in Science shows that it doesn’t have to be that way. Textiles woven from high-tech layered fibers couple with the body to scavenge electromagnetic energy from the environment—batteries not included. The textiles can also act as simple sensors that are easy to read by eye, or they can beam out a wireless signal. The research team behind the fibers includes Chengyi Hou, Hongzhi Wang, and Qinghong Zhang, who are in the college of materials science and engineering at Donghua University in Shanghai.
The group has demonstrated these smart fibers in a variety of applications. They’ve made a carpet that senses people’s footsteps, a textile-based game controller, a wearable 644-pixel display, and a textile keyboard that can be used to write messages to put on the display.
