Design of Wireless Power Transmission System based on magnetic coupling resonant for the capsule endoscopy

In order to solve the problem that the capsule endoscope is limited by energy, it can reduce the volume and weight of the capsule robot by using the external wireless power to replace the button cell. This paper proposed a miniaturized, low-power energy transmission mode based on magnetic coupling resonant WPT(Wireless Power Transmission). Based on the scheme design, we finished the contrasting experiments of the magnetic coupling resonant and magnetic induction coupling transmission in power and efficiency, completed the weighing experiments of receiving coil and button cell(CR3032), and experimental results are obtained through constructing the platform. Through this design, we solved the questions of wireless capsule endoscope battery power restrictions, improved the work efficiency.
