This paper explains that the RF systems for bi-directional wireless capsule endoscopes were designed and implemented. The designed RF systems for a capsule endoscope can transmit the images of intestines from the inside to the outside of a body and the behavior of the capsules can be controlled by an external controller simultaneously. The bi-directional wireless capsule endoscope consists of a CMOS image sensor, FPGA, LED, battery, DC to DC Converter, transmitter, receiver, and antennas. The transmitter and receiver which were used in the bi-directional capsule endoscope, were designed and fabricated with 10㎜(diameter) × 3.2㎜ (thickness) dimensions taking into the MPE, power consumption, system size, signal to noise ratio and modulation method. The RF systems designed and implemented for the bi-directional wireless capsule endoscopes system were verified by in-vivo experiments. As a result, the RF systems for the bi-directional wireless capsule endoscopes satisfied the design specifications.
