Wearable devices,as an emerging technology product,have shown great application potential in the fields of health monitoring,human-computer interaction,and aerospace.However,most wearable devices are still powered by traditional button batteries or lithium battery packs,which are rigid,bulky,with limited energy storage and short lifespan,severely limiting the application and promotion of wearable devices.The continuity of human perspiration and the fact that sweat contains a large amount of electrolytes and metabolites make it a potential source of continuous energy supply for wearable devices.Sweat battery is a new technology that utilizes human sweat as fuel to provide power,which has the advantages of lightness,softness,mild reaction conditions,highly biocompatible and wearable.This review aims to comprehensively summarize the working principles,device structures,and latest application progress of sweat batteries,hoping to provide a guide for the development of flexible sweat batteries.
