Bioinspired Dual‑Scale Crack Manipulation Enabling 325%‑Stretchable Metal Film Conductors for AI‑Empowered Electronic Skins (IMAGE)
Caption
- A leaf-inspired hierarchical architecture is developed to enable micro-nano, dual-scale crack manipulation in metal films, leading to a nearly 25-fold regulation of stretchability (from 12% to 325%).
- A stretchable metal film-based, AI-empowered electronic skin is developed, demonstrating excellent applicability in human motion monitoring, sign language translation, and speech recognition.
- The role of metal film cracking in stretchable electronics is reinterpreted, shifting from an unfavorable failure phenomenon into a powerful design tool for on-demand tuning of electromechanical properties.
