Skin-like micropumps transform human motion into fluidic flow via morphing valves (opens in new tab)

Soft, skin-conformal fluidic systems are essential for wearable healthcare; however, micropumps that rely on rigid external hardware for actuation have limited portability and on-body integration. Here, we introduce OSMiPump, a power-free, strain-driven micropump that directly converts natural human motion into unidirectional fluid transport using a soft, monolithic architecture. OSMiPump integrates out-of-surface microchannels (OSMiCs) with self-actuated valves (OSMiValves), where cyclic ten...
