Electromagnetic vibration transducers are seen as an effective way of
harvesting ambient energy for the supply of sensor monitoring systems.
Different electromagnetic coupling architectures have been employed but
no comprehensive comparison with respect to their output performance has
been carried out up to now. Electromagnetic Vibration Energy Harvesting
Devices introduces an optimization approach which is applied to
determine optimal dimensions of the components (magnet, coil and back
iron). Eight different commonly applied coupling architectures are
investigated. The results show that correct dimensions are of great
significance for maximizing the efficiency of the energy conversion. A
comparison yields the architectures with the best output performance
capability which should be preferably employed in applications. A
prototype development is used to demonstrate how the optimization
calculations can be integrated into the design-flow. Electromagnetic
Vibration Energy Harvesting Devices targets the designer of
electromagnetic vibration transducers who wishes to have a greater
in-depth understanding for maximizing the output performance.
