Abstract

The invention discloses a high-stretch flexible strain sensor based on a porous flexible material, which is mainly composed of a strain sensor body and a strain signal reading interface; The conductive material on the surface of the base and the encapsulation material are formed. The design of the internal structure of the flexible sensor skin enables it to have good stretchability, greater sensitivity and measurement range. At the same time, the internal structure of the present invention can be arranged in different arrays, so as to meet different use environments and applicable conditions.
