Wearable Electronics: Elastic Multifunctional Liquid–Metal Fibers for Harvesting Mechanical and Electromagnetic Energy and as Self‐Powered Sensors (Adv. Energy Mater. 18/2021)

In article number 2100411, Ying-Chih Lai, Michael D. Dickey and co-workers develop a naturally stretchable and elastic multifunctional liquid-metal fiber that can scavenge biomechanical energy and electromagnetic energy from surrounding electrical appliances. The multifunctional liquid-metal fiber can serve as a wearable power provider and various self-powered sensors. These findings optimally unify mechanical freedom and the capability of collecting multiple forms of ambient energy and self-powered sensing in a single fiber, opening new doors for wearable/stretchable/personal energy and sensing technologies.
