Abstract
A method for increasing the power transfer efficiency of a wireless induction power and/or data transfer system comprising a magnetic field transmitter which is positioned on a first side of a barrier and a magnetic field receiver which is positioned on a second side of the barrier opposite the first side comprises the steps of disposing at least one flux flow member in or adjacent the barrier at least partially between the transmitter and the receiver. The flux flow member comprises a magnetic permeability different from the magnetic permeability of the barrier. As a result, the flux flow member increases the amount of magnetic flux generated by the transmitter which is coupled through the barrier and into the receiver.
