This study presents a novel iontronic triboelectric gel with a phase-locked structure inspired by the biphasic nature of human subcutaneous tissue. The gel is designed for wearable haptic sensing applications, featuring excellent mechanical compliance and biomimetic properties. Competitive hydrogen bonding systems are constructed through polymer-solvent-nonsolvent interactions, leading to controlled phase separation. This results in a soft-hard alternating phase-locked structure with a Young's modulus of 6.8–281.9 kPa and high tensile strength (> 300 kPa), making it compatible with human skin. The gel exhibits strong adhesion and can form stable interfacial connections with human skin, ensuring high-fidelity transmission of haptic signals. The self-powered tactile sensing skin based on this gel maintains favorable interface and mechanical stability, enabling precise recognition of objects. The study provides a universal platform for applications in soft robotics and wearable electronics, offering broad dynamic tunability of mechanical properties.This study presents a novel iontronic triboelectric gel with a phase-locked structure inspired by the biphasic nature of human subcutaneous tissue.
