Phase‐Transition‐Driven Adaptive Reconfiguration of Wearable Devices for Conformal Biointerfaces

, tensile strength of ∼161 kPa), stretchable, and stress-free interfaces with skin. Furthermore, this robust interface permits reversible switching between strong to weak adhesion, while dissolving on-demand for painless, non-traumatic removal. We validate the approach with shape-adaptable sensors and electrodes that seamlessly wrap the vulnerable, peristaltic bodies of silkworms for motion tracking, and hairy, thorn-laden leaves for plant electrophysiology monitoring, expanding the utility of wearable electronics to previously inaccessible biological surfaces.
