Abstract

This thesis presents a detailed and practical approach to the design, assembly, and characterization
of rotary mode triboelectric nanogenerators (R-TENGs) for mechanical energy harvesting. While
TENGs have gained attention for their versatility and potential in sustainable energy applications,
working with R-TENGs remains challenging due to the lack of standardized procedures, limited
reproducibility, and sparse standardization documentation in the literature. Addressing these gaps,
this work aims to provide a clear, step-by-step foundation for constructing and understanding R-
TENG systems, with emphasis on both technical and material aspects. Experimental comparisons
between a conventional disk-type design and a novel concave/cylindrical configuration are
conducted, with attention to fabrication challenges, mechanical alignment, and output
characterization. Low-cost and accessible materials are prioritized to support broader adoption and
educational use. In addition, the thesis offers a concise yet solid introduction to the basic principles
of TENG operation, providing a comprehensive and educational reference in triboelectric energy
harvesting.
