Abstarct: This thesis introduces a fully planar wireless power transfer (WPT) scheme aiming to provide enough power for working for a capsule endoscopy. The usage of our method on patients is more convenience than that of previous conventional WPT plans in which a cylindrical wire coil is placed around the patient's body. In addition, while using the proposed printed power receiver structure, the internal space of the capsule opens up for other components such as image sensors and data transmitting components. To improve the efficiency, we used a two-laxyer printed coil as the transmitter, a two-laxyer printed coil as the receiver and a power coil on the transmitter side excited at 13.56 MHz. By this method, the efficiency increased to more than 2% in our proposed structure. The effect of body tissue on the power efficiency is also simulated and measured, and the maximum Specific Absorption Rate (SAR) value is considered for the desired system. The SAR value is 7.098 ×10-2 W/kg for 0.5 W input power and 1.5×10-1 W/kg for 1 W input power. Our results indicate that the proposed system satisfies required medical standards.
