▎ 摘　　要

NOVELTY - The sensor has a sensor body provided with a piezoelectric layer and a piezoresistive layer. The piezoelectric layer is formed with a piezoelectric micro-structure composite film. A composite thin film gold electrode is sprayed on the piezoelectric micro-structure composite film. The piezoresistive layer is formed on a graphene film, where the graphene film is provided with a micro-structured gold electrode surface. The micro-structure is satisfied in a regular quadrangular table, where the regular quadrangular table represents side length, pressure, time, voltage meter resistance and output voltage of the piezoelectric layer. USE - Dual mode sensor for detecting pressure and strain during sample testing process. ADVANTAGE - The sensor increases sensing performance characteristics to obtain strain information during testing process and simultaneously senses size, direction and strain rate of bending strain of sample. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a dual mode sensor for detecting pressure and strain during sample testing process.
