In this work, we report electrical properties of PVA(polyvinyl alcohol)-PAAm(polyacrylamide) ion gels dipped in NaCl glycerol solution and fabricated the transparent skin electrodes for long-term monitoring. The skin electrodes were fabricated by the poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) mesh, which has high electrical conductivity, biocompatibility, flexibility, higher transparency and deformability than conventional PEDOT:PSS film. This PEDOT:PSS mesh was interlocking with PVA-PAAm ion gels dipped in NaCl glycerol solution, which are non-volatile and has sufficiently high electrical properties for sensing bio-signals. Finally, the fabricated skin electrodes were used to recording electromyography (EMG) and successfully demonstrated that these skin electrode can record bio-signals. |
