“…Therefore, in our study, 433.92 MHz, which is one of the ISM frequencies, is employed for the operation. Previously, a small receiving antenna in the capsular endoscope for the WPT was proposed in [33]. However, the bandwidth of the receiving antenna was not enough because of shifting of the resonance frequency.…”

SUMMARY Recently, wearable wireless devices or terminals have become hot a topic not only in research but also in business. Implantable wireless devices can temporarily be utilized to monitor a patient's condition in an emergency situation or to identify people in highly secured places. Unlike conventional wireless devices, wearable or implantable devices are used on or in the human body. In this sense, body-centric wireless communications (BCWCs) have become a very active area of research. Radiofrequency or microwave medical devices used for cancer treatment systems and surgical operation have completely different functions, but they are used on or in the human body. In terms of research techniques, such medical devices have a lot of similarities to BCWCs. The antennas to be used in the vicinity of the human body should be safe, small and robust. Also, their interaction with the human body should be well considered. This review paper describes some of the wearable antennas as well as implantable antennas that have been studied in our laboratory. key words: wearable antenna, implantable antenna, body-centric wireless communications, RFID, hyperthermia, medical device, human body, phantom

“…In our system, we adopted a receiving antenna wraps around the capsular endoscope, which is assumed to be placed at 4 mm from the surface of intestine [7]. The receiving antenna is required to obtain power radiated from transmitting antenna outside the body.…”

“…In addition, we also discussed the directions of the capsular endoscope. The measurement system consists of a network analyzer, a power divider, the transmitting array antenna, the receiving antenna [7] and a biological equivalent phantom, as shown in Fig. 2 (b).…”

Abstract:Recently, the wireless power transmission (WPT) system is expected to employ as a means to transmit power to capsular endoscope diagnosing the digestive organs. In order to increase transmission efficiency, in this study, we proposed a transmitting spiral antenna which can transmit adequate power to the capsular endoscope with being independent of its position and direction. In this paper, we discussed the power transmission efficiency and SAR on human body by means of FDTD method and experimentation.
