Frequency Decision of Magnetic Field for Transcutaneous Wireless Energy Transmission to Capsular Endoscope for Colon Inspection

摘要

Capsular endoscopes for inspecting internal organs are operated by tiny battery cells contained, inside. For untethered capsular endoscope for colon inspection, however, these batteries may not have enough power for driving the capsule to reverse direction of the autonomous peristaltic motion of the intestines. If high frequency magnetic field is generated uniformly inside the human body and if the small capsule in the human body has wound coils. to induce the electromotive force (emf) from the surrounding magnetic field, the capsule with enough power delivery can move into the deep position of the large intestine from anus.
