A mere 100 µl water droplet impacting the surface from a 15 cm height generates over 140 V voltage, a 200 μA current, and a maximum power of 50 W m -2 , surpassing conventional droplet generator designs by several orders of magnitude. Introducing a superhydrophobic surface-based droplet electricity generator can enhance the average electrical output and robustness of a device that works at low-frequency impinging droplets.
