Stretchable and multipurpose

Electronics

By stacking and connecting layers of stretchable circuits on top of one another, engineers have developed an approach to build soft, pliable '3D stretchable electronics' that can pack a lot of functions while staying thin and small in size. The work is published in Nature Electronics.

As a proof of concept, a team led by the University of California San Diego has built a stretchable electronic patch that can be worn on the skin like a bandage and used to wirelessly monitor a variety of physical and electrical signals, from respiration, to body motion, temperature, eye movement, heart and brain activity. The device, which is as small and thick as an Indian rupee coin, can also be used to wirelessly control a robotic arm.

"Our vision is to make 3D stretchable electronics that are as multifunctional and high-performing as today's rigid electronics," said senior author Sheng Xu, a professor in the Department of NanoEngineering, UC San Diego Jacobs School of Engineering.
