From: Wearable woven supercapacitor fabrics with high energy density and load-bearing capability
(a) CV curves of a supercapacitor fabric (as shown in the inset photo) when stretched at different stresses at the scan rate of 20 mV s−1. (b) CV curves of the sample when pressed with different pressures at the scan rate of 20 mV s−1. The inset photo shows how it is tested when the sample is stepped on. (c) A photo of a load bearing supercapacitor strap with the 4-cell connect-in-series design. (d) Galvanostatic charge–discharge tests of the strap working at 4 V. (e) Capacitance retention of the strap under different bending radii. (f) Capacitance retention of the strap during 1000 bending cycles around a human wrist.
