Direct-current triboelectric nanogenerators (DC-TENG) harness the friction generated between rotating dissimilar materials and convert it to useable electrical power. One of the many potential applications of this technology is in small scale renewable energy. A wind turbine was designed in which multiple DC-TENG generators would be attached to turbine blades of varying dimensions. This project involved the design and construction of several rotating DC-TENG prototypes, followed by measuring the electrical output of each nanogenerator at various rotational speeds. A model was designed to test the application of this device as part of a multiple-rotor wind turbine, and will be constructed and studied further as part of a related Green Fee Project. This presentation will discuss the technical features of the most recent prototype, outline the design methodology which led to it, and suggest ways in which future students could improve upon the design.
