A Wearable Power Generator for Sports Monitoring Applicationsby Ursula Leonard 08331502 4th Sports and Exercise Engineering Final Year Project Supervisor: Dr. Maeve Duffy
Introduction • Background • Aims • Progress to date • Tasks Remaining • Power
Background and Aims • Electromagnetic Induction • emf rate of change of magnetic flux • Produce max AC Output • Convert to useable DC • Develop pedometer system • Possible Applications • Pedometer 1.5v – 2.5v • Accelerometer 2v – 3.4v
Optimisation of Dimensions • The Generator • Length, diameter • The Copper Coil • Length of coil • Number of coils • Diameter of wire • The Magnet • Gradient • Shape, length, diameter
Building and Testing • Card Former • One coil • Generator length 50mm • Magnet diameter 10mm • Magnet grade and length • Wire diameter • No. of turns of wire • No. of coils Constant Variable
AC/DC Conversion • Analysed conversion circuits • Half wave rectifier • Full wave rectifier • Multiplier circuits • Downloaded simulation software • Predict results • Analysed types of diodes • Silicon • Germanium • Schottky • Very low forward voltage drop
Tasks Remaining • Build conversion circuit • Get hand on transceivers • Become familiar with programming language • Write program • Program up LCD display • Accelerometer • Display speed with steps taken
Conclusion • Happy with progress to date • A lot of work ahead • Lighter Semester Thank you for your time Any Questions?
