Abstract

 

With the rapid development of Internet of Things technology, interactive interfaces that can promote bidirectional communications between human beings and machines will certainly play an important role. Current electronic or iontronic systems meet diverse requirements such as conductivity, mechanical compliance, stimuli responsiveness, long‐time duration, and even biocompatibility. However, for future large‐scale applications, non‐degradable and non‐recyclable components in these devices cause resource waste and environmental pollution. Here, traditional dough is used to replace non‐recyclable conductive components and fabricate a type of renewable and reconfigurable smart skin. These smart skins are self‐healing, mechanically adaptable to irregular interfaces, and can sense different gestures of a prosthetic hand as well as large and subtle scale of human motion. This work greatly extends the material choice and enables new functionality for skin‐like iontronics, and may address the concern about their impact on human health and environmental issues in the era of Internet of Things.
