Flexible pressure and strain sensors have great potential for applications in wearable and implantable devices, soft robots, and artificial skin. The introduction of self‐healing performance has made a positive contribution to the lifetime and stability of flexible sensors. At present, many self‐healing flexible sensors with high sensitivity have been developed to detect the signal of organism activity. The sensitivity, reliability, and stability of self‐healing flexible sensors depend on the conductive network and mechanical properties of flexible materials. This review focuses on the latest research progress of self‐healing flexible sensors. First, various repair mechanisms of self‐healing flexible materials are reviewed because these mechanisms contribute to the development of self‐healing flexible materials. Then, self‐healing elastomer flexible sensor and self‐healing hydrogel flexible sensor are introduced and discussed respectively. The research status and problems to be solved of these two types of flexible sensors are discussed in detail. Finally, this rapidly developing and promising field of self‐healing flexible sensors and devices is prospected.
