Conventional electrode materials based on metals are not suitable for flexible electrodes. Nowadays, studies have actively been conducted on three-dimentional, flexible, self-healble, and printable electrodes using the conductive polymers to solve the problems. Among the various soft materials, agarose is a natural hydrophilic polymer and forms a hydrogel that has a characterization of thermal sol-gel transition. In this study, we develop a soft hydrogel electrode that can be easily formed by using agar/activated carbon (AC) composites. Using reversible thermal sol-gel transition of agar/AC composite, we prepare various shapes of agar/AC composite gels for demonstrating agar/AC composite gel as a shape configurable electrode. In addition, quantative analysis for electrical properties of agar/AC composites proves that conductivity of composite gels can be improved up to 0.511 mS/cm. Finally, we demonstrate a simple electric circuit system with agar/AC composite gel as a electrodes. |
