▎ 摘  要

NOVELTY - The method involves using conductive light curing resin as strain sensitive material. A flexible wearable dog palm sleeve is insulated by flexible photosensitive resin, where thickness of the flexible wearable dog palm sleeve is less than 1 mm. The conductive light curing resin is made of graphene, carbon nano tube, dispersant, photosensitive prepolymer resin, thickening agent, coupling agent and solvent according to certain proportion for printing purpose. A flexible pressure sensor is manufactured by applying multi-material digital light processing three-dimensional (DLP3D) printing technology. A dog foot model is obtained by 3D scanning technology. The prepared flexible wearable dog palm sleeve is combined with the flexible pressure sensor. USE - Multi-material DLP3D printing technology based method for manufacturing a flexible pressure sensor used for monitoring foot pressure and pathological states of canines. ADVANTAGE - The method enables realizing mass production of the flexible pressure sensor in a simple and quick manner at low production cost with high sensitivity, high ductility and high stability. The method enables ensuring that the manufactured flexible pressure sensor can avoid pet wearing discomfort. DETAILED DESCRIPTION - The flexible photosensitive resin is made of 30.0-60.0 % of photosensitive prepolymer resin, 3.0-10.0 % of non-reactive resin, 20.0-50.0 % of active diluting agent, 5.0-10.0 % of photoinitiator, 0.5-1.5 % of flatting agent, and 0.3-1.5 % of polymerization inhibitor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic illustration of a multi-material DLP3D printing technology based method for manufacturing a flexible pressure sensor.
