▎ 摘　　要

NOVELTY - The method involves mixing a synergistic mixture of Zinc oxide nanoparticles with particle size distribution selected in a range of 43.8 to 712 nanometer and graphene nanoplatelets with particle size. A glass substrate is masked with tape exposing a section at the center. Zinc oxide nanoparticles-graphene nanoplatelets-ink is dispensed on an exposed section of the glass substrate with a micropipette. The glass substrate spin is coated and cured. The spin coating and curing is repeated by a first layer of polydimethylsiloxane. The masked tapes are removed from the glass substrate. Polydimethylsiloxane layer is peeled from the glass substrate to obtain an embedded sensing layer. Copper terminals are connected to the embedded sensing layer using silver epoxy. A final passivation layer of polydimethylsiloxane is poured on the embedded sensing layer and followed by curing at 80 degree Celsius for 10 minutes. USE - Process for fabrication of Zinc oxide nanoparticles-graphene nanoplatelets based flexible strain and pressure sensor. Uses include but are not limited to robotics, prosthetic devices, real-time remote health monitoring, biomechanics for sports and video gaming, and structural health monitoring. ADVANTAGE - The process provides highly flexible pressure and strain sensors with superior sensitivity and large measuring range using nano ZnO-graphene based polymeric sensors. The process has high sensitivity and wide measurement range of the sensors, and superior adhesion between the substrate and sensing layers, resulting in no deformation or peeling of the coating layer. Unlike the commonly used process which employ direct coating steps such as sputtering, chemical vapor deposition, electrochemical deposition, etc. on substrates, the process involves a unique peel-off technique for sensor deposition. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a strain/pressure sensor.
