Hydrogels have been ext.nsively st.died for applicat.ons in various fields, such as t.ssue engineering and soft.robot.cs, as det.rmined by t.eir mechanical propert.es. t.e mechanical design of hydrogels t.pically focuses on t.e modulus, t.ughness, and deformabilit.. t.ese charact.rist.cs play import.nt.roles and make great.achievement. for hydrogel use. In recent.years, a growing body of research has concent.at.d on t.e fat.gue propert. of hydrogels, which det.rmines t.eir resist.nce t. crack propagat.on in t.e net.orks during cyclic mechanical loads for applicat.ons.
