Presentation Outline
Project Re-introduction
Design Process
Major Obstacles
Major Accomplishments
Next Steps
Battery-free Tire Pressure Monitoring System
Project Re-Introduction
Design Process Utilized feasibility calculations/physics
resources Number of wraps on coil Coil diameter Magnet Orientation
Tested theories on test apparatus Adjusted design accordingly
Major Obstacles Magnet Orientation
Proper orientation gives higher voltage Proper orientation reduces the number of
magnets necessary Coil Design/Manufacturing
Compact coils Working coils
Mounting
Major Accomplishments Working test apparatus
Major Accomplishments Magnet Mounting Bracket Design
Caliper
Magnet
ThreadedHeightAdjustment
Caliper Mounting Holes
Major Accomplishments Voltage Generation
3 Volts at ~25 mph
6 Volts at ~60 mph
4.5 Volts at ~42 mph
7.5 Volts at ~75 mphAll voltages are half wave heightsAll speeds are simulated on test apparatus without a tire mounted
Readings taken at 5 V/division on Y-axis 5 ms/division on X-axis
Major Accomplishments Circuit Design Tested
Half Wave Rectifier Requires Voltage Regulator
Magnet Orientation Coil Design Improved Purchased TPMS System Budget Under Control
Next Steps Refine magnet and coil size Refine circuit design Mounting design for coil and circuit Magnet bracket construction Develop TPMS testing method
