SOY PROTEIN DERIVED HYDROGEL FOR SENSING APPLICATIONS

Invention Summary

This technology introduces the first soy protein-based double network (DN) ionic conductive hydrogel, engineered for enhanced mechanical and conductive properties. The hydrogel consists of a methacrylated soy protein isolate (MSPI) and poly(vinyl alcohol) (PVA) double network, combined with tannic acid-coated cellulose nanocrystals (TCNC) and sodium chloride (NaCl) in a glycerol-water binary solvent system

Benefits

    • Enhanced durability: Robust against mechanical stress, freezing, and drying, ensuring longevity in various environments.
    • High Performance: Exceptional strain sensitivity and response time (~300 ms), capable of detecting diverse human movements with high accuracy
    • Biocompatibility: Made from soy protein, a natural and abundant material, making it environmentally friendly and suitable for biomedical application
