Flexible Supercapacitors: Watchband‐Like Supercapacitors with Body Temperature Inducible Shape Memory Ability (Adv. Energy Mater. 16/2016)

Applications of smart watches are limited due to present design of energy storage devices. In article number 1600763, Xingbin Yan and co-workers describe for the first time the fabrication of a novel flexible solid-state supercapacitor to integrate energy storage device with a watchband. The as-assembled smart watchband exhibits excellent electrochemical stability during statical and dynamical bending. As a smart energy-support watchband, it maintains shape memory property which can be automatically induced by touching it with the human wrist.
