Wearable woven supercapacitor fabrics with high energy density and load-bearing capability

Abstract Flexible power sources with load bearing capability are attractive for modern wearable electronics. Here, free-standing supercapacitor fabrics that can store high electrical energy and sustain large mechanical loads are directly woven to be compatible with flexible systems. The prototype wi...
