The self-healing property of biological tissues gives humans inspiration to endow artificial synthetic materials with self-healing functions. Herein, we report a thermoplastic elastomer that can be self-repaired in a short time, which uses dual dynamic bonds (hydrogen bonds and disulfide bonds) coupled to realize its self-healing function through the rapid conversion of dynamic hydrogen bonds between the hard and soft segments, as well as the dynamic bonding and dissociation of disulfide bonds. Furthermore, the maximum tensile strength and strain of the elastomer can reach 17.4 MPa and 3780%, respectively, and the maximum self-healing rate is close to 100% (temperature: 90 °C, time: 5 h). The arrays’ arrangement and reversibility of hydrogen bonds endow the elastomer with high toughness and self-healing properties and thus solve the problem that ordinary polymers cannot self-heal.

Recently, researchers have been focused on the developing flexible electronics for detecting both kinds of information without disturbing the robot itself much.Over the past decades, electronic skins (e-skins) have been attempted to enable robots to interact with their environment more precisely, quickly, and safely. [26][27][28] However, the e-skins are usually single function for force, pressure, temperature, humidity, and approximate sensing, which cannot fulfill the requirements for the robot operation. [25,27,28] Many attempts have been done to develop multimodal perception e-skins, [29][30][31][32][33][34][35][36] which can be divided into three parts. First, it is to integrate multiple sensors in a side-by-side or stacked manner. [29][30][31] Second, it is to use the multidimensional-sensing properties of materials for simultaneous multidimensional information sensing, including graphene, carbon nanotubes, and triboelectric nanogenerators, which mainly performs comprehensive detection of pressure, temperature, and humidity based on the principles of piezoresistance, capacity, or triboelectricity. [32][33][34][35][36][37] Third, it is to unify as a detection method to achieve integrated perception, which is mainly based on the principle that the resistance changes due to the different heat transfers between the thermal

“…When force is applied to a capacitive sensor, the distance or the area of the plates changes, and the capacitance changes accordingly. Employing this principle, wearable sensors can be made using nanomaterials that measure capacitive strain [73][74][75][76][77][78][79][80]. A novel capacitive strain sensor using CNTs demonstrates good durability with a strain range between 1% and 300% [81].…”
