英文摘要	With the continuous development of wearable sensing devices utilized for human motion monitoring, structural health monitoring, and robotic systems, higher demands on a set of material properties of functional materials are placed. Moreover, high flexibility and self-healability are indispensable properties in wearable electronic devices. Herein, a self-healing flexible dielectric nanocomposite with various incorporated functionalities is described. Multidimensional carbons, that is, graphene and carbon nanotubes, are introduced into a self-healing polyurethane matrix to obtain the healable dielectricnanocomposite which contributes to the capacitance response of the wearable sensors. The as-prepared nanocomposite exhibits a dramatic increase in properties, which reach up to 10.50 +/- 0.44 MPa for Young's modulus, 35.1 for dielectric constant at 10(3) Hz, and 1.67 W m(-1) K-1 for the in-plane thermal conductivity with low loading. More importantly, the nanocomposites display a unique ability to recover the structure and multiple properties after mechanical damages. In addition, a self-healing capacitive strain sensor with the "sandwich" structure is prepared based on the nanocomposite. The strainsensor shows good sensitivity in a larger strain range (up to 100%), stable responsiveness, and healable ability.
