A stretchable conductor based on shrinkable fiber mat for wearable joule heating

Abstract

Wearable heaters have attracted great interest worldwide due to their significant applications in thermal therapy and keeping warm. Here, a strain-insensitive conductor was developed by depositing a thin layer of gold film on a shrinkable fiber mat. The conductor showed high stretchability and strain insensitivity. When the conductor was used for joule heating, it demonstrated high stability and reliability even during stretching.
