We are interested in recruiting anMEng student for the study of piezoelectric based energy harvesters. Piezoelectric energy harvesters are typically beams that have been laminated with piezoelectric material. Tip masses are added to tune the beams to resonate at a specific frequency. We have developed a method of optimizing the layout of these beams for maximum power production. By varying the layer thicknesses in the beam, our analysis shows a point where power is maximized. This project would involve validating this analysis experimentally.
The experimental validation would require the use of our lab equipment including but not limited to a laser vibrometer, oscilloscope, function generator, shaker, and possibly labview. We are looking for a student who has taken vibrations and possibly mechatronics (there are very simple circuits involved). The beams will have been previously fabricated.
