Abstract
The self-healing properties and mechanosensing capabilities of the human skin have inspired the design of stretchable iontronic sensors. However, existing mechanasensitive designs can hardly achieve autonomously superior self-healing properties and effective control of ion dynamics in a homogeneous system simultaneously. Herein, we report a Cl-functionalized iontronic pressure sensitive material via the introduction of Cl-functionalized groups into a polyurethane matrix, which realizes an ultrafast, autonomous self-healing speed (4.3 µm/min), high self-healing efficiency (91% within 60 min), and mechanosensitive piezo-ionic dynamics. This strategy promotes effective control of ion dynamics via ion-dipole interactions, resulting in excellent pressure sensitivity (7.36 kPa−1) for tactile sensors. The skin-like sensor responds to pressure variations, demonstrating its potential for touch modulation in future wearable soft electronics and human–machine interfaces.
