Stretchable VO/PEDOT supercapacitors: a modular fabrication process and charging with triboelectric nanogenerators.

Stretchable energy storage devices are of great importance for the viable applications of wearable/stretchable electronics. Studies on stretchable energy storage devices, especially supercapacitors (SCs), have shown encouraging progress. However, challenges still remain in the pursuit of high specific capacitances and facile fabrication methods.
