Content Overview • • • PDS requirements Internal/External Search Evaluation of top 7 ideas Decision Matrix Top 3 ideas Conclusion

PDS Requirements • • Geometry : 3 mm thick Airflow : 0. 01 – 0. 1 cfm Air Speed : 0. 1 – 1 m/s Air Pressure : 0. 01 – 0. 05 IWG

Internal/External Search • Research based • Anything that moved air • Current products • Creating ideas from research

Top 7 ideas • • Tesla Turbine Magnetic membrane 2 pistons pump Mini bellows Piezoelectric Plate diaphragm Wave pump

1. Telsa Turbine • Stacked spaced rotating discs • Uses shear boundary layer

2. Magnetic Membrane • Magnetically actuated membrane

3. 2 piston pump • Rotating crank moves piston to replicate lung or heart (inhale/exhale)

4. Mini Bellows • Bellows that uses a magnet to open/close

5. Piezo electric membrane • Vibrating membrane as a result of current • Expels air with quick motion

6. Plate Diaphragm • Plate rotating about joint • Pushes air with rotation

7. Wave Pump • Waving membrane • Transfers air in pockets

Decision Matrix

Top 3 • Magnetic membrane • Mini bellows • Piezo electric membrane

Final Concept • Ordered piezoelectric material • Test will determine our decision
