Abstract
Authors have been continued examination to use UHF band RFID tags for location management of a patient. The problem using UHF band RFID to attach human body are the permittivity of human body and water which reduce wavelength and attenuation of UHF band transmitted signals, so it is difficult to translate when attached on human body. Thus in the past 125kHz and 13.56MHz band RFID has been use for attach human body but are useless for location management cause of its short distance of translation. To avoid influence metal behind the tags high magnetic permeability sheet are work but does not work for human body. We found that the gap about 10mm from human body are good to avoid its influence and make capable for location management of patient without bad influence for medical equipment. To attach human body tags must have no damage for it. We use polyolefin like material for its chemical stability and low skin stimulus. And use flexible material and roundish shape to not to lost living quality of patient. Actually few members attached it for a month had no damage for translation and had not lost of living quality. Our low cost tags can use disposable and hygienic.
