Electronic skin (e-skin) mimicking functionalities and mechanical properties of natural skin can find broad applications. We here demonstrate a robust yet rehealable, fully recyclable and malleable e-skin based on dynamic covalent thermoset doped with conductive silver nanoparticles. Tactile, temperature, flow and humidity sensing capabilities are realized. The e-skin can be rehealed when it’s damaged, and can be fully recycled at room temperature. After rehealing or recycling, the e-skin regains mechanical and electrical properties comparable to the original e-skin. In addition, malleability enables the e-skin to permanently conform to complex, curved surfaces without introducing excessive interfacial stresses. These properties of the e-skin yield an economical and eco-friendly technology that can find broad applications in robotics, prosthetics, healthcare and human-computer interface.
