Estimation of Harvesting Power in Magnetic Energy Harvesting Module using Bobbin Coils

In this paper, bobbin coils are used as magnetic energy harvesting coils. Bobbin coils are low cost and have a high degree of freedom of shape. An equation is proposed to estimate the harvesting power of a magnetic energy harvesting coil from the mass and bobbin size of the bobbin coil. Electromagnetic induction experiments with the bobbin coil were carried out and the relative error to the harvesting power obtained confirms the agreement with the trend of the estimation equation.
