▎ 摘　　要

NOVELTY - The pressure sensor is manufactured by preparing polymer micro-nano fiber as a framework using electrostatic spinning process, coating graphene as a conductive active layer on the outer layer of framework, to prepare sensitive layer of the sensor, transferring the sensitive layer to polydimethylsiloxane substrate, finally, another layer of polydimethylsiloxane is formed covering the composite film onto sealing device, and assembling flexible resistant type pressure sensor. USE - Flexible resistant type pressure sensor for detecting human body pulse. ADVANTAGE - The pressure sensor is obtained with high sensitivity, fast response speed and stable response performance. The pulse detection capability is improved.
