Physical bonding method of hydrogel and elastomer and hydrogel tension sensor

The invention discloses a physical bonding method of hydrogel and an elastomer and a hydrogel tension sensor, and the physical bonding method comprises the following steps: dissolving a first polymer in an organic solvent to obtain a polymer solution; adding sacrificial particles into the polymer solution, and stirring to obtain a porous polymer mixed solution; coating the porous polymer mixed solution on the surface of an elastomer, removing part of the sacrificial particles and all the organic solvent through a sacrificial template method, and forming a porous high-molecular polymer film on the surface of the elastomer to obtain a porous elastomer composite material; and coating the surface of the porous high-molecular polymer film of the porous elastomer composite material with the hydrogel sol to carry out crosslinking treatment so as to realize physical bonding of the hydrogel and the elastomer. By introducing the porous high-molecular polymer film between the hydrogel and the elastomer, firm physical in
