Fig. 5: Demonstration of the high-performance MG-based TENG.
a Photograph of experimental setup of the TENG with high gas pressure. Charge output at a different gas pressure of b Cu/PTFE pair and c MG/PTFE pair. d Summary of the surface charge density of different material pairs at different gas pressure, with the theoretical line compared. e Setup of the MG-based T-TENG. f Photograph for powered LEDs. g QSC (top) and VOC (bottom) of MG-based T-TENG. h Current output of the device at resistance of 1kΩ. i The peak current and peak power, j the peak current density and peak power density depending on the load resistance. Here, the MG sample is Zr45Cu40Al15. The scale bar was 1 cm. k Comparison of peak power density of this work to other work. (Reference information: No.1: Reproduced with permission46.
