Monitoring, control and diagnostics using RFID infrastructure

This work demonstrates the developed application for disinfection control by the sensing of chemical agents. The objective was to develop an Automatic Disinfectant Tracker (ADT) that would verify the disinfection of the hands of nurses, doctors, staff, patients, and visitors in hospitals within a required time frame. We have successfully investigated the development of hand disinfection control mechanisms and demonstrated two approaches, both based on the wireless Ultra-High-Frequency-based Radio-Frequency Identification (UHF-RFID) technology. The 100 % efficacy of detecting propanol and ethanol concentration was achieved by using the static disinfectant control (SDC-ADT) method. The time domain response provides an accurate determination of their performance in practice simply by measuring the applied disinfectant concentration and the duration of application. The present paper resulted from the measurements of a capacitive chemical sensor fabricated in the Laboratory for Microelectronics, (LMFE) and on measurements, based on a commercially available resistive type of sensor. A graphic user interface (IDS-GUI) is designed to successfully set the logger parameters and display the results.
