Comparison of Electromagnetic Energy Harvesters

This paper compares various types of electromagnetic harvesters in terms of their electrical and magnetic features. The harvesters have different flux morphologies and natural frequencies and therefore that can be a superiority for them to use in different applications from the ignition signal to the energy harvester aims for battery-free systems. It will be pointed out that the systems considered here have the power ranges of P = 14 mW and P = 32 mu W for the optimal frequency regimes.
