WIRELESS POWER TRANSMISSION APPARATUS, WIRELESS POWER TRANSMISSION SYSTEM INCLUDING THE SAME AND WIRELESS POWER TRANSMISSION METHOD THEREOF

摘要

Provided is a wireless power transmission including a power supplying unit configured to output external power as a power signal having a set frequency, a power transmitting unit configured to output the power signal from the power supplying unit as a wireless power signal of an EMF type, and a controller configured to output a power control signal for controlling an output level of the wireless power signal, wherein the controller calculates a SAR and inner body temperature variation amount by using EMF and temperature measurement data transmitted from the implantable medical device in the power transmission process, and outputs the power control signal according to a result of comparing the calculated SAR and inner body temperature variation amount with a reference value.
