Lim, Joonwon Choi, Dong Sung Lee, Gil Yong Lee, Ho Jin Padmajan Sasikala, Suchithra Lee, Kyung Eun Kang, Seok Hun Kim, Sang Ouk Omnidirectional Deformable Energy Textile for Human Joint Movement Compatible Energy Storage Omnidirectional deformability is an unavoidable basic requirement for wearable devices to accommodate human daily motion particularly at human joints. We demonstrate omnidirectionally bendable and stretchable textile-based electrochemical capacitor that retains high power performance under complex mechanical deformation. Judicious synergistic hybrid structure of woven elastic polymer yarns with carbon nanotubes and conductive polymers offers reliable electrical and electrochemical activity even under repeated cycles of severe complex deformation modes. The textile-based electrochemical capacitors exhibit omnidirectional stretchability with 93% of capacitance retention under repeated 50% omnidirectional stretching condition while demonstrating excellent specific capacitance (412 mF cm<sup>–2</sup>) and cycle stability (>2000 stretch). The wearable power source stably powers red LED under omnidirectional stretching that accompanies human elbow joint motion. stretchable textile-based electrochemical capacitor;wearable power source stably powers;polymer yarns;power performance;textile-based electrochemical capacitors exhibit omnidirectional stretchability;omnidirectionally bendable;Human Joint Movement Compatible Energy Storage Omnidirectional deformability;LED;wearable devices;deformation modes;electrochemical activity;conductive polymers;carbon nanotubes;Omnidirectional Deformable Energy Textile;capacitance retention 2017-11-07
