Abstract

Current single-stage water-enabled electric generators waste energy by discharging water after single use. This paper proposes a multi-stage coupling water-enabled electric generator (mc-WEG) that uses both liquid flow and moisture to generate electricity, achieving a maximum power density of -92 mW m⁻². A customizable design allows for varied energy output, with 22 units in series powering a table lamp for 30 minutes. The mc-WEG shows flexibility and environmental adaptability.
