Investigation of Wireless Power Transfer System with Different Coil Structures used in Wireless Capsule Endoscope

摘要

Biomedical Implant Systems are low power high frequency operated systems, particularly in this paper authors proposes the Wireless Capsule Endoscopic Implant with Wireless Power Transfer where we generally use batteries. The PTC Configuration used here is a basic solenoid/combined Helmholtz coil and PRC used here is 3D PRC which enables the different Orientations of Capsule all through the Small Intestine. The PTE is about 0.02-3.5% range and that too in the worst misaligned position it was observed as 1.088% operating at 246 KHz frequency. Mixed Resonance Scheme allows delivering more Power to the Load, also ensuring the Reasonable Uniform Magnetic Field Intensity around the coils.
