Liquid Metal Superelastic Fiber Mat Enabling Highly Permeable Wearable Electronics Toward Comfortable e-Skins

Low water vapor and air permeability is a persistent challenge in wearable and on-skin electronics,as it reduces wearing comfort,and leads to skin irritation and inflammation in the long term.To tackle this issue,Zheng and coworkers designed a stretchable conductor based on an elastomeric fiber mat coated by liquid metal.
