Engineering Strain‐Stiffening Granular Hydrogels for 3D‐Printed Tissue‐Mimicry
Advanced Materials, EarlyView.A 3D‐printable strain‐stiffening double‐network granular hydrogel (SDGH) enables independent, region‐specific tuning of toe (EToe) and heel (EHeel) moduli through control of microgel packing and network composition. This platform replicates tissue‐like nonlinear mechanics and allows fabrication of high‐fidelity, multilayered aortic valves with ...
