This thesis describes the working design principles of triboelectric mechanism-based devices. It presents an extensive study undertaken to explain the effect of surface topographies on the performance of triboelectric nanogenerators. It demonstrates the application of triboelectric mechanisms in the area of physical sensing such as force sensing and pressure sensing. It also discusses the major fabrication methods/techniques that can be used to realize these devices. It is a valuable reference resource for graduate students, researchers and scientists interested in exploring the potential of triboelectric mechanisms for energy harvesting and other applications.
