Liquid–metal-bridge∼island design: seamless integration of intrinsically stretchable liquid metal circuits and mechanically deformable structures for ultra-stretchable all-solid-state rechargeable Zn–air battery arrays

The demonstrated “liquid-metal-bridge∼island” architecture enables the fabrication of ultra-stretchable solid-state micro-Zn–air battery arrays with tunable open circuit voltage/peak power (1.35–5.24 V/38–145 mW), large elongation (400%), and excellent integration capability.
