 M-Zine Hydrogels offer promising prospects for flexible and wearable electronics due to their unique properties such as stretchability, self-adhesion, transparency, and biocompatibility. These properties make them suitable candidates for applications in flexible electronics, human-machine interfaces, sensors, actuators, etc. Additionally, M-Zine Hydrogels benefit from their surfaces being negatively charged, high-specific surface area, facile functionalization, and high metallic conductivity. However, stability remains a challenge for M-Zine-based applications, which can be improved by incorporating M-Zine Hydrogels into existing Hydrogels. This paper reviews the current state of knowledge on M-Zine Hydrogels, discusses their design strategies, preparation methods, and applications in wearable electronics.
