The treatment, diagnosis, and monitoring of diseases have attracted more and more attention in recent years. Healthcare electronics help effectively treat and real-time monitor diseases. Triboelectric nanogenerators (TENGs) show great potential for healthcare applications because of their superiority including low cost, flexible structures, and self-powered property. Herein, the recent key advancements in TENG-based healthcare applications are comprehensively reviewed. TENGs could not only harvest the mechanical energy from the body to make electrical stimulation but also generate different electrical signals in response to external stimuli. Integrated systems combined with TENGs and other sensors could also promote sensing stability. The materials, structures, working mechanisms, and performance of each application are discussed. The existing limitations and prospects for further TENG-based healthcare are finally put forward.
