Description
technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a flexible and stretchable sensor and its preparation method and application. Background technique [0002] Flexible wearable electronic products are used in wearable human health monitoring and nursing systems, which have the functions of monitoring human motion and disease prevention, and thus have received more and more attention. Carbon nanotubes have the advantages of good electrical conductivity, large aspect ratio, excellent flexibility, light weight, high chemical and thermal stability, etc., and with the functionalization of carbon nanotubes and mass production, they become flexible and wearable. A strong candidate material for electronics. In order to further improve the application effect of carbon nanotubes (Carbon NanoTube, referred to as CNT) in wearable strain sensors, researchers have developed CNTs with various forms, such as ordered CNT arrays, CNT ...
