  • Shape morphing soft materials and assemblies including the same
    Patent number: 11492434
    Abstract: A hydrogel precursor composition includes 10 wt % to 40 wt % N-isopropylacrylamide, 0.5 wt % to 2 wt % N,N?-methylenebisacrylamide, a solvent, and a photoinitiator. The hydrogel precursor composition is photocurable and thermally responsive. A thermally responsive hydrogel is formed by photopolymerizing the hydrogel precursor composition. The thermally responsive hydrogel may be used to mimic the activity of muscle fibers.
    Type: Grant
