Project Description:

This research project will focus on the design and fabrication of a new family of triboelectric nanogenerator to harvest mechanical energy and convert it into electricity. Triboelectrification is a commonly observed effect in our daily life and is usually viewed as a negative effect (e.g., electrostatic shock). Recently, great attention has been devoted to taking advantage of the charge transfer during periodic contact and separation as well as rubbing of a pair of triboelectric friction materials. The objective is to use this natural phenomenon to generate electricity. Recent research revealed that an energy conversion efficiency of ~50-85% can be achieved.

In this research, various micro-and-nanostructuring techniques will be investigated on a set of triboelectric materials to elucidate the structure-to-property relationship of the materials. Prototypes of triboelectric nanogenerators will be designed and developed to demonstrate the potentials of using these materials to harvest all kinds of mechanical energy that is available in our daily life, such as human motion, walking, vibration, mechanical triggering, rotation energy, wind, a moving vehicle, rain drops, …etc.

Students participating in this project will gain hands-on experience in a wide range of state-of-the-art and industrial viable material processing and characterization technologies. These include compounding, molding, supercritical CO2 foaming, differential scanning calorimetry, scanning electronic microscopy, analyzers for electrical properties…etc.
