ABSTRACT

As a compact electronic device, the flexible and stretchable sensor has attracted attention due to its wide application field, including environmental signal detection and human body physiological signal monitoring. This type of sensor has advantages such as being portable, lightweight, and easy to make compared with traditional sensors with rigid structures. Since polymers are the main component of these sensors, the healable properties from intermolecular and intramolecular interaction provide unique characteristics to flexible sensors, which strongly enhances their robustness during long-term use. In this chapter, a concise review of the healing mechanisms, materials, device design concepts, and typical applications is provided to give a brief picture of the recent development of sensors with flexibility, stretchability, and healability.
