•Water droplet electrical energy harvesting system.•Charge dynamics for rolling/sliding and bouncing droplets.•Charging of capacitor increases with droplet density and decreases when a continuous film is formed.•Model for volume flow rate-dependent charging of the external capacitor.
Recent research has demonstrated that electrical energy can be harvested when water droplets move over a hydrophobic polymer covered by a single electrode on its back-side. Here we study the charge dynamics as water droplets pass the polymer. We also investigate how the charging of an external capacitor changes with water flow volume rate, and present a model to understand the results.
