▎ 摘　　要

NOVELTY - Sensor has an elastic substrate provided with middle slit (3) and an edge slit (4) to form a paper cutting structure. The middle slit is formed as a hollow rectangle formed by cutting a middle unit of the elastic substrate (5). The edge slit is a hollow U-shaped unit that is fixed by cutting an edge of an inner side of an outer layer package. A conductive material comprises a strain sensitive conductivity material and a strain non-sensitive conductivity material (2). The conductive materials are arranged on the elastic substrates in a serpentine structure and do not interfere with the intermediate slit and the edge slit. The strain sensitive conductor material is arranged along a length direction of an elastic substrate. The non-strain sensitive conductive device is arranged on an elastic structure along a width direction of the substrate and is connected with the strain sensitive conducting device. The outer layer packaging encapsulates the conductive devices on the substrate. USE - Extensible strain sensor of multi-material paper cutting structure for detecting various human body physiological activity, human-machine interaction, health monitoring and flexible electronic skin. ADVANTAGE - The strain sensor has important practical value for improving the single-direction strain precision and finger bending adaptability, which can effectively reduce the deformation error of the non-detection direction of the strain sensor when the finger bends and deform, and better adapt to the large-angle bending requirement through the self-expanding deformation of the paper-cut structure slit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing extensible strain sensor with multi-material paper cutting structure. DESCRIPTION OF DRAWING(S) - The drawing shows structure of extensible strain sensor with multi-material paper cutting structure. (Drawing includes non-English language text).
