  1. Energy Harvesting Group #10January 20, 2011Preliminary Design Review for EE495B Capstone Senior Design Faculty Project Lead: Dr. Ralph Whaley Team Members: Jared Booth, Thomas Caston, Nathan Grubb, Nate Warren Stakeholders: Dr. Whaley, Ohio University, Russ College of Engineering and Sujit Chemburkar, Baker University Center

  2. Project Review • Create energy harvesting floor mat • Place floor mat in Baker Center • Harvest mechanical energy of footsteps • Store energy in rechargeable battery. • Changes • Removing PIC reading display due to time and money constraints

  3. Project Goals • To successfully create an energy harvesting device. • Successfully store energy in an energy storing bank. • To charge an electronic device via USB output. • Safely place energy harvesting device inside Baker Center at Ohio University.

  4. Design Content • Division of Group • Mat Design • Research and design an energy harvesting device. • Storage Device • Design device to store harvested energy.

  5. Functional Requirements • Energy Harvesting Mat Dimensions – 3’ x 3’ x ½” • Max mat height of 1” • Storage Unit Box Dimensions – 10” x 10 “ x 10” • Rectifier Circuitry • Rechargeable Battery Pack • Mat Material • Must be made of durable, non slip, and water resistant material. • Piezoelectric Coax Cable • Outside Diameter of 0.105”.

  6. Flow Chart PIEZOELECTRIC MAT Capacitor Battery USB

  7. Operational Requirements • Piezoelectric Coax Cable • Generate electric current when mechanical force is applied. • For our purpose: • Mechanical force  Electric charge • Piezoelectricity has many useful applications

  8. Mat Design Idea

  9. Energy Harvesting Circuitry

  10. Group Project Hours • Hours to Date – 108 Hours • Dr. Whaley and Baker Center Meetings – 48 Hours • Research - 40 Hours • Group Design Meetings – 20 Hours • Projected Hours – 192 to 222 Hours • Dr. Whaley and Baker Center Meetings – 72 Hours • Research – 40 Hours • Group Design Meetings – 30 Hours • Project Construction Hours – 50 to 80 Hours • Total Project Hours = 300 to 330 Hours

  11. Updated VOC • Additional Stakeholder • Sujit Chemburkar Executive Director Baker University Center . • Change in customer demand. • Mat Placement (Location & Time) • Application • Future use of technology

  12. Value to The Customer

  13. Our Method • Use piezoelectric coax cable to generate mechanical energy. • Surround the piezoelectric coax cable with a durable mat. • Have a storage device to store harvested energy. • The electricity will then be used to charge a small device using a USB port.

  14. GANNT Chart

  15. Project Deliverables • Prototype • Save money • Design • Analysis • Recommendations for next generation upgrades. • Final design review.

  16. Previous Coursework • EE – 101 (Basic Circuit Analysis) • EE – 210 (Intermediate Circuit Analysis) • EE – 221 (Instrumentation Lab) • EE – 454 (Power Electronics) • EE – 490 (Power Systems)

  17. Constraints • Money • $500 Budget • Piezoelectric Materials • Piezoelectric Chips • Durability and Reliability • Piezoelectric Cable • Unknown Voltage Response • Deadline • June 2011

  18. Risk & Mitigation • Safety Hazard • Mat will be no larger than ¾” • Slip Resistant mat • Bright Color • Theft • Metal Security Box • Maintenance • Easily relocated

  19. Budget • Spent Thus Far • $0.00 • Projected Costs • Piezoelectric Material - $200.00 • Mat Material - $100.00 • Remaining Circuitry - $200.00

  20. Summary • What has changed. • Different design options • Stakeholders • Location • Application • Future Steps. • Acquire data from piezoelectric coax cable testing. • Determine mat design and circuitry through collected data. • Analyze Baker Center pedestrian flow for the best possible location of mat. • Order remaining project materials. • Complete project prototype.
