The sustainable operation of wearable /implantable medical devices is crucial for the next generation of personalized medicine. However, limited battery capacity is a critical challenge for most wearable /implantable medical electronics. The human body is rich in mechanical and chemical energy (such as respiration, exercise, blood circulation, oxidation and reduction of glucose, etc.), so it is considered a feasible method to obtain mechanical energy from the body to supply power for wearable /implantable medical electronics. A variety of new methods for developing in vivo energy harvesters have been proposed to power wearable /implantable medical electronics. Based on this background, we here focus on the recent research progress of energy harvesters based on piezoelectric or triboelectric effects, with an emphasis on the fabrication, materials design, energy output, durability, as well as their typical applications in biomedicine and evaluation criteria. Finally, according to the actual needs of wearable /implantable medical electronics, the prospects and challenges of nanogenerators are discussed.
