AI Technical Summary
Existing ionogel sensors have limited mechanical strength, are easily damaged, and have insufficient adhesion in robotic skin applications, making it difficult to meet the requirements for high sensitivity and long-term reliability.
Employing a semi-interpenetrating polymer network structure, a self-healing ionic gel is formed through a cross-linked network of linear polyacrylic acid and poly(hydroxyethyl acrylate-co-hydroxyethyl methacrylate). Combined with dynamic reversible hydrogen bonds and ion-dipole interactions, a continuous ion transport channel is constructed, enhancing mechanical strength and self-healing ability.
It achieves high sensitivity, fast response and excellent environmental stability, has self-healing capabilities, and adapts to the robot's skin for efficient perception and durability in complex environments.
