Design of inductive coil for wireless power transfer

Recent advancements in the miniaturised electronics and embedded system are wide spread in the various fields of engineering applications. From bio-medical implants to actuating device for monitoring pressure and temperature for industrial applications have been developed in wide spread. Wireless power transfer application to such device may tap the full potential of such system and seems to be a viable option in many cases of low power devices. The study of power transfer including the performance of inductive link at radio frequency is dealt in the paper. Theoretical studies are backed up with a practical experiment of charging a cell phone which is dealt at the end of the paper.
