Abstract

Abstract: Monitoring various medical information distributed throughout the body is of great importance in early clinic diagnosis and treatment of disease. To discover abnormal medical signals and find their causes in good time, the human body should be monitored continuously and accurately. To meet the requirements, various battery‐less and self‐powered information acquisition techniques are invented. In this review, the recent advances in self‐powered medical information sensors (SMIS) with different functions, structure design, and electric performance are summarized and discussed. The SMIS mainly involves triboelectric nanogenerator (TENG), piezoelectric nanogenerator (PENG), pyroelectric nanogenerator (PyNG)/ thermoelectric generator (TEG) and solar cell. Additionally, this review also analyzed the remaining challenges and prospected the development direction of SMIS in future. Abstract : The monitoring of physiological signals is of important significance for the early detection and timely treatment of diseases. Self‐powered medical sensors (SPMS) provide a new effective technique to obtain various physiological signals from body without battery. This review highlights the recent advance of SPMS in sensor types, device structure, electric performance and application scenarios. Viewpoints on present challenges and future development trends are also discussed.
