Hydrophilic hydrogels exhibit good mechanical properties and biocompatibility, whereas hydrophobic elastomers show excellent stability, mechanical firmness, and waterproofing in various environments. Hydrogel-elastomer hybrid material devices show varied application prospects in the field of bioelectronics. In this paper, the research progress in hydrogel-elastomer adhesion in recent years, including the hydrogel-elastomer adhesion mechanism, adhesion method, and applications in the bioelectronics field, is reviewed. Finally, the research status of adhesion between hydrogels and elastomers is presented.
Keywords: adhesion mechanism; adhesion method; applications in bioelectronics; hydrogel–elastomer adhesion.
