Scientists invent biodegradable battery that controls the beating of hearts

Scientists at the University of Oxford have developed a groundbreaking biodegradable lithium-ion battery that can control biological tissues, including mouse hearts, for potential use in treating cardiac arrhythmia. The battery, made of biocompatible hydrogel droplets, is light-activated, rechargeable, and small enough to interact with living organisms. This innovation could lead to the development of tiny smart devices for biomedical applications, as detailed in the study published in Nature Chemical Engineering.
