An Enhanced Liquid Metal Triboelectric Nanogenerator (LM-TENG) Using Parallel Placement of Friction Layer

We reported a LM-TENG using a hierarchical micro/nano textured nonwetting surface immersed into a liquid metal bath in vertical direction previously. In this work, we report a great improvement in LM-TENG output power which uses a parallel placement of hierarchical micro/nano textured nonwetting friction surface in a liquid metal bath, instead of vertical sliding immersion method. This new method shows a 4,401% enhancement in output power compared to our previous work. The CF4/O-2 plasma-etched Kapton friction layer-based LM-TENG was able to harvest energy continuously without loss of a performance during the non-stop 24 hours of testing while showing a maximum peak harvested power of similar to 16.88 mu W.
