Localization method using received signal strength for wireless power transmission of capsule endoscope

In recent years, capsule endoscopy has attracted attention as a medical device that examines the internal digestive tract without burdening the patient. Wireless power transmission of the capsule endoscope is researching now, and the power transmission efficiency can be improved by knowing the capsule location. In this report, we try to use the three-dimensional localization method with five antennas.
