  8. Guidance/Navigation

  9. Structural Health Monitoring

  10. Sports Medicine: Concussions

  11. FitBit and Nike Fuel

  12. Accelerometer Design: Frequency Response • Very low r values = good design

  13. Accelerometer Design: Phase Lag -f

  14. The Problem with Phase Lag If not designed properly, phase lag causes the measured signal to deviate from the actual acceleration. (Above example would be for a BAD design.). Ideally, you want to design for zero phase distortion.

  15. Where does damping come from? Dynamic viscosity of air c Squeeze Film Damping: Thin film of air interacts with silicon masses in motion
