Contact electrification (CE) and electrostatic induction (EI) are believed to be the core processes in classic liquid-solid triboelectric nanogenerators (L-S TENGs), including classical transistor-like droplet-based electricity generator (DEG) other forms of DEGs. Recently reported total current DEGs made full use CE, EI, charge transfer (CT) effects realized coupling displacement conducting currents. However, this method has only been revealed special structures, which have limitations depending on falling location droplets. Here, we construct a press-release DEG (PRTC-DEG) using single droplet water visually verify universality CT contribution DEG. By simply squeezing then releasing PRTC-DEG, charges squirted out realize separation space time. The working mechanism PRTC-DEG between also demonstrated. In addition, structural design proposed study alleviates dependence output droplets provides new mode for DEG, makes expand more scenarios.
