Abstract Elastomer‐based resistive super‐thin film strain sensors show great application potentials in electronic skins, human–machine interaction systems, wearable devices for healthcare, and machine learning algorithms. However, it is challenging to accurately monitor the deformation of human body joints organs with curved surfaces (e.g., knees, throats, finger joints) by only taking advantage material thickness elasticity conventional 2D sensors. Herein, a simple strategy developed fabricate conformal elastomeric thin periodic 3D microstructure inspired ridges valleys skin accurate signal acquisition. Specifically, an 8‐micrometer‐thick elastic sensor fabricated via thermoforming followed situ chemical growth silver nanoparticles. The exhibit excellent linearity (R 2 = 0.99) relatively high sensitivity (gauge factor 14) over wide range (≈43%), ultra‐low detection limit 0.025%, enabling potential applications healthcare monitoring air leakage detection. Thus, this study unveils methodology process microstructure‐enabled conformable sensors, which good conformability multiple mechanical sensing functions advancing development next‐generation flexible
