▎ 摘  要

NOVELTY - The method involves combining the graphene dispersion liquid with the thermoplastic polyurethane three-dimensional film formed by electrostatic spinning and vacuum filtering to form a composite film, where the mass ratio of the polyurethane 3D film and the graphene oxide is 1:4-1:6. The composite film in an ascorbic acid solution for the reduction reaction to obtain a dual-response sensing material is soaked. The dual response sensing material is made into a sensor. The mass ratio of the 3D film to graphene oxide is 1:5. USE - Preparation method of flexible wearable temperature pressure double-response sensor. Uses include but are not limited to electronic skin, human-computer interaction, robot, motion detection and health monitoring system. ADVANTAGE - The method enables to prepare flexible wearable temperature pressure double-response sensor that is capable of directly with the pressure resistance and temperature double- response of the human skin contact, and has great application potential. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the flexible wearable temperature and pressure dual-response sensor.
