Fudan University develops stretchable fiber super-capacitors

Professor Peng Huisheng and his colleagues from Fudan University have developed super-capacitors — devices that store electric charge — in the form of highly stretchable fibers, which can be woven into textiles.

It’s hailed as the first truly wearable electronics in the world. And the research result has been published in Nature magazine in the United States and Angewandte Chemie magazine in Germany. Angewandte Chemie means applied chemistry.

Wearable electronics require stretchy components, but such parts are often flat sheets, which limits their ability to be incorporated into fabrics. And the super-capacitors developed by Fudan University can be curved, folded and extended.

The super-capacitors can maintain their function when extended by up to 75 percent.
