WIRELESS POWER TRANSMISSION APPARATUS, WIRELESS POWER TRANSMISSION SYSTEM INCLUDING THE SAME AND WIRELESS POWER TRANSMISSION METHOD THEREOF
First Claim
1. A wireless power transmission apparatus that wirelessly transmits power to an implantable medical device, the wireless power transmission apparatus comprising:
- a power supplying unit configured to output a power signal having a set frequency as an external power;
a power transmitting unit configured to input the power signal from the power supplying unit and to output a wireless power signal of an electromagnetic field (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 specific absorption rate (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.
