▎ 摘　　要

NOVELTY - Preparing high-strength eutectic gel, comprises mixing a eutectic solvent, water, a gel reinforcing agent and aqueous polyurethane to obtain a homogeneous solution, orderly performing thermal curing and ultraviolet light irradiation reduction to obtain the final product, where the eutectic solvent comprises a hydrogen bond acceptor and a hydrogen bond donor. The gel reinforcing agent is aqueous solution of oxidized graphene or MXene aqueous solution. USE - The high-strength eutectic gel is useful in the field of strain sensor (claimed). ADVANTAGE - The eutectic gel: is not easy to fall off; has excellent ultra-sensitive performance, high elasticity, transparent conductivity, high thermal stability and low volatility; and can real time monitor the human body pulse signal. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a high-strength eutectic gel prepared by the above-mentioned method; and a strain sensor, comprising high-strength eutectic gel and copper foil, where the high-strength eutectic copper gel is connected with the copper foil.
