Abstract

AbstractImplantable energy harvesters (IEHs) are the essential and required component for self-powered medical devices. IEHs is employed as the primary power source of implantable medical electronics by harvesting the energy from living organisms such as respiration, heartbeat, and chemical energy from the redox reaction of glucose. In this chapter, IEHs and self-powered implantable medical electronics (SIMEs) are summarized. The typical IEHs are based on ultrasonic or optical energy such as biofuel cells, nanogenerators, electromagnetic generators, and transcutaneous energy harvesting devices. A benefit from these in vivo energy harvesting technologies, SIMEs emerged, including nerve/muscle stimulators, cardiac pacemakers, and physiological sensors. The challenges and potential solutions related to IEHs and SIMEs are also provided.
