Optimization Wireless Power Transfer Using Simulation Relevant Parameters

Academics and the medical industry are both very interested in wireless power transfer (WPT) in medical implanted devices (MIDs). These systems have had issues with their battery life, which requires charging or replacement. Wireless power transfer in implantable medical devices is significantly hampered by the size of the coils for energy transmission and reception. Analytical calculations can be used to determine the output power of a wireless power transfer system, but it is more challenging to determine the effects of selecting a specific design or material for the transmission and receiving coil assembly. The impact of altering the distance between the transmitter coil and receiver, materials, geometries, and number of turns on output power is quantified in this work by numerical modeling. The quantifications acquired made it possible to choose a coupling coefficient model and compute the best parameters for the power transfer. The study helps to discover the crucial variables that need to be changed or managed in the coils in order to maximize the transmission of power for a wireless system.
