No-Load Analysis of Permanent Magnet Spring Nonlinear Resonant Generator for Human Motion Energy Harvesting

Abstract:

With the structure of permanent magnet (PM) spring, composed of one fixed end magnet and one moving magnet, a nonlinear resonant electromagnetic generator is designed for harvesting energy from human wrist by vertical shaking, which can be used as an emergency power source for portable electronic products, such as cell phone. The magnetic field distribution is analyzed by finite element method (FEM). Generator model is built under no-load condition and the parasitic damping factor is evaluated indirectly. The model is amended through reasonable hypothesis of collision and validated by the measured results, which can be used for further with-load analysis and generator optimization.
