Hydrogel-based sensors that detect human motion have attracted significant attention. However, it is still difficult to make a tough hydrogel sensor with good skin adhesion. This study aims to fabricate a protein-based hydrogel using sodium caseinate (SC), a milk protein, for high adhesion, biocompatibility, high stretchability and good toughness. In the SC-AAm hydrogel, sodium caseinate micelles and acrylamide (AAm) chains impart mechanical toughness, and hydrogen bonds enable repeated adhesion to the skin. In addition, the introduction of 2-acrylamido-2-methylpropanesulfonic acid (AMPS) imparts conductivity to the hydrogel, allowing it to act as a sensor capable of responding to various human movements such as fingers, knees, elbow bends, and deep breathing. |
