▎ 摘　　要

NOVELTY - Fiber type triboelectric strain sensor comprises fiber substrate layer orderly arranged from inner side to outer side. A working electrode layer and packaging layer are arranged in sequence from inside to outside. The material of fiber base layer is flexible and stretchable polymer with good biological compatibility. A conductive material is provided on material of a working electrode sheet. A flexible stretchable polymers is provided in packaging layer. The fiber base layers and working electrode layers are placed in package layer. A spiral line or a snake-shaped structure is fixed on periphery of fibers base layer. USE - Fiber type triboelectric strain sensor. ADVANTAGE - The fiber type triboelectric strain sensor has light weight, low cost characteristics, excellent wearing experience and simple manufacturing process, and does not need external power supply to realize strain detection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing fiber-type triboelectric strain sensor, which involves: a. performing rotary inkjet printing technology. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of fiber type triboelectric strain sensor.
