Monitoring, Control and Diagnostics using RFID Infrastructure

Abstract

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.

Monitoring Pharmacy Student Adherence to World Health Organization Hand Hygiene Indications Using Radio Frequency Identification

“…Their system was able to determine the relative location on all personnel in the room (in patient care zone or not), and had between 60%-100% accuracy in determining the number of surgical sponges in use depending on their location. 6 Although this may seem to have a small impact on pharmacists directly; RFID systems may be potentially implemented to determine the location of personnel (including pharmacists) in patient care areas to determine proximity in the event of a medical/medication error. 6 Students volunteered to participate over a consecutive 5-day period, but performance varied widely and was generally below what we expected based on the WHO indications and the number of class periods.…”

We did not account for student attendance in class, so it is possible that some of the demonstrated nonadherence to hand hygiene may actually be attributable to absence from class.…”

“…Study designs varied widely, resulting in comparative efficacy rates of 52.4 to 100% compared to direct observation. [4][5][6][7] This range may be attributable to study design factors, such as adherence to wearing the RFID tags and radio interference from other equipment.…”

Read Range Enhancement of a Sensing RFID Tag by Photovoltaic Panel

“…Concerning RFID architectures with sensors, microcontrollers can be used in combination with RFID chips and different types of sensors (e.g., temperature, light, and moisture content [4][5][6][7]; chemical sensing [8][9][10][11][12]; pressure [13]; general RFID platforms for different sensing applications [14][15][16]; surface acoustic wave (SAW) sensors [17] or built-in sensors; and typically temperature sensors [18]). There are also some examples of single chip architecture without a microcontroller unit [19][20][21][22][23]. In these strategies, the main advantage compared to the analog read of the tag is the direct processing of the sensor data in the RFID tag.…”

Printed single-chip UHF passive radio frequency identification tags with sensing capability

“…Other approaches are based on microcontroller architectures with RFID chips and different types of sensors: temperature, light, moisture content [32,33]; chemical sensing [7,[34][35][36][37][38]; printed moisture sensors [4,5,12,13]; pressure [39]; or built-in sensors, typically temperature sensors [40]. There are also some examples of single chip architecture without microcontroller unit already reported [41][42][43]. The main advantage of this strategy compared to the analogue reading of the tag is the fact that sensor data are directly processed in the RFID tag.…”
