(551e) Bioresorbable Aqueous Batteries for Self-Powered Biomedical Devices

Conventional batteries are widely used for energy storage; however, they are often non-degradable, use toxic components, and are harmful to humans, which discourages their use in biocompatible applications. In this talk, I will introduce our research on biocompatible and bioresorbable batteries and their applications in self-powered biomedical devices. Bioresorbable materials fully degrade after a period of stable operation in the human body, minimizing waste and eliminating the need for surgical extraction. The emergence of bioresorbable materials in recent years presents an opportunity to develop bioresorbable batteries. The talk will start with the introduction of bioresorbable batteries, followed by a discussion of different types of bioresorbable batteries and their electrochemical performance [ref. 1]. Finally, I will present our studies on self-powered miniaturized biomedical devices for electrotherapy [ref. 2] and drug delivery [ref. 3].
