Energy harvesting using magnetic induction considering different core materials

Energy harvesting is an emerging area with a wide range of low-energy applications and consists of capturing very small amounts of energy from one or more naturally-occurring energy sources (e.g. solar, thermal, wind, kinetic, etc.), accumulating and storing them. Recently, energy harvesting based on magnetic induction is gaining more and more attention because of their promising performance in power grid since energy can be harvested by the wasted magnetic field around power line using the principle of electrical transformer. However, the performance of the induction-based harvester presents very different results according to the magnetic core material used. In this work, it is presented experimental results on induction-based harvester considering the power density achieved by different magnetic core materials.
