  1. Piezoelectric Energy Harvesting ARSLAN MAJID ECE DEPARTMENT UNIVERSITY OF UTAH

  2. Overview • Energy harvesting • Piezoelectricity • Future outlook [1]

  3. Energy Harvesting • What is it? • Macro scale- wind and solar • Micro scale- electromagnetic and piezoelectricity [3] [2]

  4. Piezoelectricity • What is it? • Occurs in polycrystalline materials • (For example: Quartz, lead-zirconate-titanate, Rochelle salt, etc.) [4]

  5. Piezoelectricity- Output • Output always different • High voltage, low current • Sample output: [6]

  6. Future Outlook [7]
