Abstract
In this paper the possibility of utilizing magnetic fields of magnetic resonant imag- ing (MRI) scanners for energy harvesting is investigated. The magnetic energy is converted into electric energy supplying small sensor systems that can be used for interventional medical appli- cations within an MRI scanner. Suitable magnetic field components for energy harvesting are analyzed and a corresponding inductor design is discussed. Accordingly, a power electronic circuit is developed and successfully tested within an MRI scanner wirelessly powered by an inductor.
