There has been a great deal of interest in minimizing the mechanical mismatches between soft tissue and soft electronics for reducing invasiveness. However, conventional soft electronics are made of polymers with high Young’s modulus like polyimide and Polydimethylsiloxane (PDMS). To minimize invasiveness, hydrogels have widely been used. Although few research groups have developed the hydrogel-based soft electronics, those still have challenges for long-term reliabilities due to swelling and drying properties of hydrogels. Herein, we report an unconventional approach for coating hydrophobic monomers to various hydrogels at room temperature with rapid coating method. The anti-swelling and -drying coating can be complete within 10 min. Hydrogels coated with hydrophobic monomers can maintain their original shape more than 7 day. The coating method we develop can be used to various hydrogels which have low melting point such as gelatin, agarose-based hydrogel. |
