A parallel double helix wire‐shaped supercapacitor protocol has been developed by H. Li, T. Zhai and co‐workers, presented on page 1024. Two symmetric titanium@MnO 2 fiber electrodes are wound on a flexible nylon fiber by a simple and reliable process. Due to rational structure design, the devices demonstrate excellent mechanical and electrochemical stability under both static and dynamic deformations. The electrochemical performance of devices under dynamic bending is found to be related to the bending frequency, and the relationship between them has been uncovered.
