▎ 摘  要

NOVELTY - Preparing adhesive photonic crystal hydrogel sensor comprises dissolving and dispersing acrylamide, acryloyl-L-phenylalanine, polyethyleneimine and cross-linking agent in solvent, adding graphene dispersion and initiator to prepare pre-polymerization solution, filling the photonic crystal with the prepolymerized solution, and preparing the viscous photonic crystal hydrogel sensor by polymerization under ultraviolet light. USE - The hydrogel sensor is useful in technical field of wear-resistant motion sensors (claimed), daily exercise monitoring and exercise monitoring of rehabilitation training patients, and underwater wear. ADVANTAGE - The hydrogel sensor: does not need to use external power supply; has sensitive stretching and discoloration performance and electrical signal change performance; has excellent viscosity; can conveniently worn without the aid of auxiliary tools; can closely attached to the skin; is not easy to fall off; and at the same time, improves the accuracy of motion monitoring. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for adhesive photonic crystal hydrogel sensor prepared by the preparation method.
