Flexible phase\u2010change materials (PCMs) are promising for wearable systems because they can integrate thermal regulation, physiological sensing and energy harvesting. Here, inspired by the hierarchical architecture of rice leaves, we report a phase\u2010change elastomer for ambient energy harvesting and ultrafast moisture sensing, fabricated via an in situ biomimetic assembly strategy. A continuous 3D segregated network of carboxymethyl chitosan coordinated with Cu\n                    <jats:sup>2+<\/jats:sup>\n                    ions spatially confines polyethylene glycol (PEG) within a poly(ethylene vinyl acetate) (EVA) matrix. This biomimetic network enables a toughness of 9.80\u00a0MJ m\n                    <jats:sup>\u22123<\/jats:sup>\n                    and an elongation at break of 218%. Unlike conventional PEG composites that are prone to humidity\u2010induced instability, the elastomer exhibits enhanced moisture resistance and a reduced leakage rate of 1.46%. Continuous ionic pathways within the segregated network enable an ultrafast humidity response of 172\u00a0ms, whereas the Cu\n                    <jats:sup>2+<\/jats:sup>\n                    \u2010containing network provides broad\u2010spectrum antibacterial activity.
