Rheological characterization of granular hydrogels, either without or with AgNPs. a) Storage modulus (G′ at 1 Hz) of the granular hydrogels. Unpaired t‐test, *p < 0.05. b) Storage modulus (G′, filled symbol) and loss modulus (G″, open symbol) as a function of strain (0.1–1000%, 1 Hz). c) Evaluation of self‐recovery of the granular hydrogels under alternating strains of 1% and 1000%. d) Macroscopic ejection of the conductive granular hydrogel ((+)AgNPs) from a 27 gauge needle. e) Shear viscosity with increasing shear rates (0.02–100 s−1) of granular hydrogels.
