Granular hydrogels are flexible and deformable, offering therapeutic and technological advantages. Granular hydrogels for biomedical use have a size of tens to hundreds of micrometers and are mainly manufactured from natural or synthetic materials with excellent biocompatibility. Because these hydrogels also affect drug release and cell proliferation and differentiation, their mechanical properties must be properly controlled for safe use. Therefore, research is actively being conducted to evaluate mechanical properties and expand the field of application. Elasticity, which represents the mechanical properties of hydrogels, is resistance to deformation, and can generally be expressed by three types of elastic modulus: young's modulus (E), shear modulus (G), and bulk modulus (K). In this study, we measured the shear modulus and compressive modulus of granular hydrogel, analyzed the changes, and investigated the possibility of applying it as a material with multiple functions.
