Continuous glucose monitoring systems (CGMs) and insulin pumps for diabetes management require reliable batteries to operate seamlessly, delivering insulin and monitoring glucose levels without interruption.[563] Similarly, artificial hearts or ventricular assist devices (VADs), which support or replace the pumping function of the heart, depend on advanced battery systems to ensure life‐sustaining performance.[564] These applications highlight the critical role of energy storage technologies in providing sustainable power solutions for life‐saving medical devices. Here, INS is linked to diabetes mellitus.
