Paper Title:
Nonlinear Resonant Generator for Harvesting Energy from Human Wrist Vertical Shaking
  Abstract

Based on the structure of permanent magnet (PM) spring, composed of one fixed end magnet and one moving magnet, a nonlinear resonant electromagnetic micro-generator is designed, which is suitable for human wrist vertical shaking and can be used as an emergency power source for portable electronic products, such as cell phone. Generator model is built under the condition of resistive load, which has been solved numerically through simulation. The model is validated by the measured results and can be used for further study of generator optimization and power processing circuits. The experimental results show that the prototype could generate power as high as 50 mW under the condition of simple harmonic driving acceleration with the amplitude of 0.8 g (7.84 m/s2) and the frequency of 3.33 Hz.
