of intelligent adaptable materials with unprecedented
sensitivity that can mimic the tactile sensing functions of natural
skin is a major driving force in the realization of artificial intelligence.
Herein, we judiciously designed and synthesized a series of lauryl
acrylate-based polymeric organogels with high transparency, mechanical
adaptability, self-healing properties, and adhesive capability. Moreover,
a robust capacitive sensor with high sensitivity (0.293 kPa–1) was developed by sandwiching the prepared soft, adaptable organogels
between two tough conductive hydrogels and then used to monitor various
human motions such as finger stretching, wrist bending, and throat
movement during chewing. Interestingly, the resulting capacitive sensor
could also function as prosthetic skin on a pneumatic soft artificial
hand, enabling intelligent haptic perception. The research disclosed
herein is expected to provide insights into the rational design of
artificial human-like skins with unprecedented functionalities.
