▎ 摘　　要

NOVELTY - The sensor has a strain-sensitive region provided with a porous graphene film to cover a porous graphene thin film of a polymer elastomer coating layer, where the polymeric elastomer is polydimethylsiloxane (PDMS), Silicon rubber or polyurethane rubber. The polymer elastomer coating layer of polymer elastomer is filled with voids of the porous graphene film, where the porous Graphene film is laser induced Graphene film and porosity of the porous Graphene film is 25 %-65 %. The porous Graphene film is formed with a pattern in a vortex along linear direction. The polymeric elastomer is thermally formed on the porous Graphene film applied by liquid. USE - Porous graphene heart sound detection sensor. ADVANTAGE - The sensor is especially suitable for a wearable heart sound detecting device, and has high sensitivity impact by the porous graphene, and avoids loose porous graphene structure, and is not easy to cause damage of failure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a porous graphene heart sound detection sensor manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a porous graphene heart sound detection sensor.
