Despite the promising progress in conductive hydrogels made with pure con-ducting polymer,great challenges remain in the interface adhesion and robustness in long-term monitoring.To address these challenges,Prof.Seung Hwan Ko and Taek-Soo Kim's team introduced a laser-induced phase separation and adhesion method for fabricating conductive hydrogels consisting of pure poly(3,4-ethylenedioxythiophene):polystyrene sulfonate on polymer substrates.The laser-induced phase separation and adhesion treated conducting polymers can be selectively transformed into conductive hydrogels that exhibit wet conductivities of 101.4 S cm-1 with a spatial resolution down to 5 μm.Moreover,they maintain impedance and charge-storage capacity even after l h of sonication.The micropatterned electrode arrays demonstrate their potential in long-term in vivo signal record-ings,highlighting their promising role in the field of bioelectronics.
