Body-Attachable and Stretchable Multisensors Integrated with Wirelessly Rechargeable Energy Storage Devices

摘要

A stretchable multisensor system is successfully demonstrated with an integrated energy-storage device, an array of micro-supercapacitors that can be repeatedly charged via a wireless radio-frequency power receiver on the same stretchable polymer substrate. The integrated devices are interconnected by a liquid-metal interconnection and operate stably without noticeable performance degradation under strain due to the skin attachment, and a uniaxial strain up to 50%.
