Triboelectric nanogenerators (TENGs) provide a simple and effective method to collect low-frequency mechanical energy. TENGs combined with the human body can collect biomechanical energy and convert it into electrical signals to monitor human body activities through four basic working modes. At present, TENGs have made great progress in the application of motion sensing, man–machine interfaces, medical care, and so on. This paper summarizes the basic working modes and principle of TENGs, the factors affecting the output performance of TENGs, as well as the research progress of TENGs as self-powered human body sensors at present and makes a prospect for the future.
