The rapid advancement and clinical deployment of bioelectronics systems for biological signal monitoring and therapy have led to an increased need for flexible and soft biomedical electronics. These electronics are specifically designed to seamlessly integrate with 3D dynamically curved biological interfaces. In this context, the development of micro-power sources, integral to these systems, is of paramount importance. These power sources must offer continuous energy supply, minimizing the need for frequent recharging or component replacement. Traditional microelectronics power units, often rigid or bulky, pose challenges such as immunological rejection and trauma, and typically fail to deliver sufficient output power for long-term applications. To effectively address these issues, there is a pressing demand for flexible, high-performance energy storage systems. These systems should not only be capable of conforming to curved bio-interfaces but also ensure long-term stability and reliability for the sustained operation of bioelectronics systems. The integration of such advanced micro-power sources into 3D soft system designs is crucial for the next generation of bioelectronics, offering enhanced compatibility and functionality for a wide range of biomedical applications.
