Advantageous properties of hydrogels makes them indispensable for applications in flexible and wearable devices. However, it is challenge to integrate multiple properties of hydrogel, such as self-adhesion, stretchability, conductivity, stable sensitivity. Moreover, developing an easy preparation method is desirable for a practical application of hydrogel. Herein, multi-functional hydrogel was prepared by rapid photo polymerization of AMPSs and AAm in the presence of sodium caseinate. The hydrogel shows tight reversible adhesion on various substrates and exhibits an out-standing stretchability, excellent fatigue-resilience. Polymeric ionic charge carrier not only endowed a high ionic conductivity to hydrogel, but also structural stability, resulting an excellent signal stability of hydrogel. Our developed approach offers a promising solution for wearable strain sensors to detect human body motion with long service life. |
