Droplet, EarlyView.A hand‐powered and mechanically programmable electrowetting‐on‐dielectric platform is demonstrated by integrating a contact‐separation triboelectric nanogenerator with a mechanically encoded punch‐card switch array. This unified mechanical–electrical architecture enables autonomous, portable, and robust droplet control for field‐deployable microfluidic
