These conductive hydrogels can have mechanical properties mimicking soft tissues, injectability, or adhesiveness, which makes them useful in soft electrodes for electromyography , wearable electrical stimulators, cardiac monitoring, in vivo nerve stimulation, and neural recording. The most common approaches to preparing these functional conductive hydrogels are (1) blending a conductive polymer with a non-conductive crosslinked hydrogel with the properties of interest, (2) blending a conductive polymer with a hydrogel precursor then crosslinking the blend, or (3) oxidatively polymerizing the conducting polymer in the hydrogel or its precursor solution. While effective, all these approaches rely on covalent crosslinkers leading to the lack of reversibility in the gelation process. Recently, Pappa and coworkers reported an example of crosslinker-free gelation using a mixture of chitosan, gelatin, and PEDOT:PSS. However, these blends are liquid at physiological temperature which limits their applicability in in vivo and in vitro bioelectronics.
