ABSTRACT Skin‐like wearable electronics have emerged as a transformative technology for next‐generation human–computer interaction, offering unprecedented compatibility with the body's soft, curvilinear surfaces, and dynamic movements. However, the scarcity of intrinsically stretchable material components and the limited coverage of reported sensors have significantly restricted their applications and accurate signal detection. Here, for the first time, we demonstrate a full‐skin‐coverage design of the intrinsically stretchable proximity sensors, fabricated using the traditional photolithographic technique with intrinsically stretchable sensor components. Their low Young's modulus and elastic nature enable seamless conformal wrapping of 1868 sensors on the hand, achieving 360° stereoscopic coverage that effectively eliminates detection blind spots. Full functionality with detectable capacitance and current signals for position and shape perception of both conductors and insulators is maintained under stretching, with a maximum tolerable strain of 30%. The unique full‐coverage capability, combined with the photolithographic strategy, enables accurate identification of both single‐ and multiposition object perception with high resolution. This work provides a generalized strategy for full‐skin‐coverage sensors, with broad implications for next‐generation soft robots, prosthetics, and human–machine interaction.
