Basic Characteristics of RFID Antenna for Urination Detection

Abstract:

Radio frequency identification (RFID) system has been expected to be expanded in new fields. This paper shows a sensing system for urination by embedding an RFID tag into a paper diaper. The urination could be checked by change of the antenna characteristics. It could be possible to reduce physical and mental strain of both patients and their care personnel. In order to detect the urination, the RFID antenna was designed and the characteristics of the antenna were calculated. In addition, the antenna characteristics were measured with a phantom. As the result, urination considerably changes the antenna characteristics and that the system can be used to detect the urination.
