▎ 摘　　要

NOVELTY - The method involves preparing a surface with multiple strip-shaped flexible substrates in parallel to each other. A graphene layer (5) is prepared on a flexible substrate (6). A graphene layer is covered on a strip-shaped structure (2). Stretching force of a stretching state is released to obtain a fluorinated structure. A surface of a graphene layer of the strip-shaped structure is formed to be fluorinated with wrinkles. A to-be-fluinated structure is fluorinated to obtain a tension sensor. USE - Method for preparing a tension sensor (claimed) used in motion detection, medical monitoring and human-machine interface. ADVANTAGE - The method enables preparing the tension sensor with simple orientation and characteristics technique, and can distinguish the strain direction of the tension sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow diagram of an optional tension sensor. 2First strip-shaped structure 3Sacrificial layer 4Modified layer 5Graphene layer 6Flexible substrate 7Imprinting mold 51First pleated structure 52Fold structure 301Second strip-shaped structure
