Abstract(in English) | In recent years, RFID systems have been widely used in the medical field to ameliorate life of patients. In the field of dental care wireless tags are implanted to dentures and used for confirmation of dentures. Conventional wireless tags are supposed to be used in the in-body environment, and it is difficult to communicate outside the body. If dentures are accidentally swallowed or lost, it is necessary to distinguish between the in-body and out-body and figure out the location of the dentures. We have proposed a RFID system that can communicate in in-body/out-body by using different frequencies. In this paper, since the conventional tag for in-body causes mismatch outside the body, the mismatch is corrected by applying a matching circuit to the IC chip. We proposed a small wireless tag and 920 MHz for in-body and 5.02 GHz for out-body, then prototyped it, and measured the communication distance. It was confirmed that communication was possible up to 30 cm in in-body condition and 27 cm in out-body condition. |
