Abstract :
This paper presents the design and realization of wireless capsule endoscopy. For this system, the optimum frequency band is investigated to maximize the overall efficiency. To achieve low power consumption, a simple On-Off Keying (OOK) transmitter is utilized. To detect the transmitted signal from within the body, an external receiver adopted a superheterodyne structure and exhibited a sensitivity of -80dBm at BER 10-5. The system operates at up to 20Mbps. The OOK system is demonstrated in internally in a pig´s body, showing clear internal body photos.
