(a) The section view of the schematic design of the vibration energy harvesting device. Dimension of each part is: for the solenoid, for the magnet pair including the gap in between, for the mounting frame on one side and on the other. (b) Magnet pair with antiparallel magnetic moment provides maximum magnetic flux change.
(a) Measured and calculated results of the open circuit voltage for the energy harvesting device at the mechanical vibration frequency 54 Hz, acceleration 0.57 g . (b) Normalized magnetic flux as a function of time and free end amplitude, at vibration frequency 54 Hz, acceleration 0.57 g.
(a) Measured and calculated frequency response of the energy harvester. (b) Elastic potential energy, magnetic potential energy, and total potential energy of the oscillation system as functions of free end displacement of the beam.
