In the field of precision medicine, advancements in electronics and microfabrication have significantly enhanced interest in miniaturized implantable biosensor devices. These devices convert biological responses into electrical signals and are used in various medical applications, including continuous patient monitoring and diagnostics. The concept of “Body Dust” emerges as a novel approach to implantable and wearable sensors, envisioning a network of thousands of sub-micrometer sensors that provide detailed information about a patient’s metabolism from within their bloodstream. One of the primary challenges is powering these sensors. Onboard batteries would increase the device’s size and require future replacements. Therefore, alternative power solutions are crucial.
