High output triboelectric nanogenerator based on scotch tape for self-powered flexible electrics

The development of wearable electronics has attracted wide publicity. However, conventional batteries will face environmental pollution and cyclic charging. In this work, we report a novel washable textile triboelectric nanogenerators (WT-TENG) based on the transparent tape film and the polytetrafluoroethylene (PTFE) film. The WT-TENG can still maintain stable output performance after being cleaned for many times. Meanwhile, due to the high hydrophobicity of the triboelectric materials, the WT-TENG has good humidity resistance. According to the results, the maximumV(oc)andI(sc)of WT-TENG (size: 3 cm x 3 cm) can reach 378 V and 63.6 mu A, respectively. And the maximum output power can arrive at 3.325 mW. The WT-TENG can be directly used to drive some commercial light-emitting diodes (LEDs). With good stability, WT-TENG can harvest human motion mechanical energy. We think our work can open a new path for expanding self-powered wearable electronics.
