katherine-medina on 22 Aug 23We find that when a falling water droplet spreads on the PTFE surface, it bridges the originally disconnected components (the PTFE/ITO and aluminum electrode) into a closed-loop, electrical system Interesting.

Fig. 1 | Design of the DEG. a, Schematic diagram. b, Optical image showing four parallel DEG devices fabricated on a glass substrate. The volume of each droplet is 100.0 μl. c, As individual droplets continue to impinge on the asfabricated device, the amount of charge on the PTFE surface increases gradually and eventually reaches a stable value. d, One hundred commercial LEDs can be powered when one droplet, released from a height of 15.0 cm, is in contact with the device. e, Under the same experimental conditions (for example, the same droplet size and height of release), the output voltage measured from the DEG (in red, with the frequency of impinging droplets being
