Core Viewpoint - The article discusses the development of a biodegradable biohydrogel battery that addresses the limitations of traditional batteries in biomedical applications, particularly their poor biocompatibility and non-degradability [3][6]. Group 1: Research Development - A research team from Zhejiang University has developed a flexible, biodegradable battery using light polymerization 3D printing technology, which maintains a stable current of 0.001 - 6 mA at a voltage of 1.5 V [3][7]. - The biohydrogel battery exhibits high printing precision of 50 micrometers, with tensile strain and compression rates of 200% and 95%, respectively, matching the mechanical properties of biological tissues [7]. Group 2: Applications and Functionality - The biohydrogel battery can operate in dual current modes, providing microcurrents (0.001 - 1 mA) to promote tissue regeneration and higher currents (1 - 6 mA) for effective cardiac pacing, offering new avenues for tissue stimulation and biomedical applications [3][7]. - The battery utilizes a conductive ion-type chondroitin sulfate methacrylate-gelatin methacrylate hydrogel and InGa3-Cu nanoparticles as electrolyte and electrode materials, respectively, showcasing excellent mechanical properties and biocompatibility [6][7].
