Development of IT utilized care support system for fruitful aging society : Detection of urine in the diaper by using IC tag.

在全球范围内，人口老龄化正在迅速进行。老龄化带来了几个问题，特别是尿液护理、初潮和痴呆症是老年人的三大问题。为解决老年人的尿液护理问题，研制了一次性尿布尿液检测系统。为此，使用了一种包含运算放大器和A/D转换器的特殊类型的RFID。为了检测尿液，尿布内放置了两个电极。它们各自具有不同的电离倾向，并能在尿液中产生电压。通过A/D转换器将电压转换为数字数据，并将来自RFID的数据传输到老年护理中心。这一体系可以在社会上形成居家养老网络。该系统可以检测尿布中的尿量，可以最大限度地利用一次性尿布。通过使用该系统，将极大地提高老年人的泌尿系统护理质量。此外，该系统还可以减少处理过程中的二氧化碳排放量。因为处理尿布会消耗大量的能量。一次性尿布的数量迅速增加，世界将消耗巨大的能源。这项研究将节省大量的能源。

Aging of the population is rapidly ongoing on global basis. Several problems are caused by aging, especially urinary care , debubitus and dementia are three big problems for elderly people. To solve the urinary care for elders, IT utilized detecting system of urine for the disposable diaper was developed. Special type of the RFID which contain op amp and A/D converter was used for this purpose. To detect urine, two electrode were placed inside the diaper. They have deferent ionization tendency individually and can generate electric voltage in urine. The voltage is converted to the digital data by A/D converter and the data from RFID can be transmitted to the care center for elders. This system can induce home care network in society. This system can detect the urinary volume in the diaper and disposable diaper can be used to the maximum capacity. By using this system, quality of urinary care for elderly people will be dramatically improved. Furthermore, this system can reduce the CO2 output for dispose. Because plenty amount of energy is consumed to dispose the diaper. Number of the disposable diaper has been rapidly increased and tremendous energy will be consumed in the world. Huge amount of energy will be saved by this study.
