The realization of conformal and reliable adhesion on textured surfaces has drawn considerable interest for precise and stable monitoring of diverse motion behaviors. However, it still remains a challenge for the achievement of skinlike membranes with favorable conformality and adhesion features in a facile and efficient way. In this work, we propose an interface-enabled approach to develop elastic and conductive Janus membranes with a controllable partially cured elastomeric layer for high conformity and adjustable adhesive property. The Janus membrane on the water surface can be readily transferred onto the targeted planar and nonplanar surfaces for final complete curing with improved adhesion. The achieved membrane can be integrated into wearable conformal electronics to effectively detect and differentiate the forward/reverse deformation of fingers with high signal stability. Moreover, it can highly adapt to the hierarchically creased paper surface for the real-time detection of the paper-folding behavior. Inspired by the wrinkled structure of the elephant trunk, an artificial wrinkled trunk was designed for motion detection. The conformal membrane on the wrinkled trunk can experience reversible contacted and/or stretched state for trunk motion behavior detection.
