Powering up stretchy technology

Nanowerk  December 30,2020 Implantable devices need electronics that can be integrated with soft tissue and accommodate the motion of the body. A team of researchers in the US (Michigan State University, Duke University, Oak Ridge National Laboratory) is working on “plant wearables,” which are sensors for crops that can stretch and bend as the plants grow and move. To power these devices they used 4D printing to create supercapacitors that can stretch to new limits without compromising their electrochemical performance. The team used an aerosol jet printer to directly deposit a specially formulated ink onto a stretchable polymer substrate. The […]
