With the increasing demands in healthcare, wearable and implantable devices are now crucial in preventing and treating patients' conditions. However, the current battery technology used in these devices has become a significant barrier to further advancements. To tackle this, many research centres are now concentrating on key principles of human physiology and employing new, innovative materials and structural designs within battery cells to enhance factors such as size, biocompatibility, and overall cell efficiency. Although considerable momentum and significant breakthroughs are being achieved concerning greater flexibility and biocompatibility, battery cells remain imperfect, and enhancements are still required in several areas to develop a truly next-generational battery. To offer a current perspective on the situation, this research article seeks to present a concise overview of the current challenges and future prospects associated with next-generation batteries for wearable and implantable devices.
