▎ 摘　　要

NOVELTY - Composite material comprises a self-healing polymer matrix and at least two conductive nanomaterials embedded, where the polymer matrix has a multi-layer structure comprising a first layer comprising a network of a first nanomaterial, which resistance changes in response to a mechanical damage inflicted on the polymer matrix, and a second layer comprising a network of a second nanomaterial, configured to generate heat under applied voltage. The network of the first nanomaterial and the network of the second nanomaterial are electrically connected to a mutual control circuit which is configured to apply voltage to the network of the second nanomaterial upon a change in resistance of the network of the first nanomaterial. The first layer is v on top of the second layer. The network of the first nanomaterial and the network of the second nanomaterial are arranged at the same vertical location of the composite material. USE - The composite material is useful in printed and soft electronics for wearable devices and electronic skins for prosthetics and robotics to marine soft electronic, and electronic skin applications, and as a self-repair composite material. ADVANTAGE - The composite material has high self-healing efficiency, electronic and mechanical properties, elastomer-like properties, thermoplastic processability, recyclability and flexibility, and allows very efficient and rapid healing of small- and big-scale damages. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a sensing platform unit.
