investigation of the impact of Infrared sensors on core body temperature monitoring by comparing measurement sites
Sensors, 2020Co-Authors: Hsuan Yu Chen, Andrew Chen, Chiachung ChenAbstract:Many types of Thermometers have been developed to measure body temperature. Infrared Thermometers (IRT) are fast, convenient and ease to use. Two types of Infrared Thermometers are uses to measure body temperature: tympanic and forehead. With the spread of COVID-19 coronavirus, forehead temperature measurement is used widely to screen people for the illness. The performance of this type of device and the criteria for screening are worth studying. This study evaluated the performance of two types of tympanic Infrared Thermometers and an industrial Infrared Thermometer. The results showed that these Infrared Thermometers provide good precision. A fixed offset between tympanic and forehead temperature were found. The measurement values for wrist temperature show significant offsets with the tympanic temperature and cannot be used to screen fevers. The standard operating procedure (SOP) for the measurement of body temperature using an Infrared Thermometer was proposed. The suggestion threshold for the forehead temperature is 36 °C for screening of fever. The body temperature of a person who is possibly ill is then measured using a tympanic Infrared Thermometer for the purpose of a double check.

Determining the emissivity and temperature of building materials by Infrared Thermometer
Construction and Building Materials, 2016Co-Authors: Hsuan Yu Chen, Chiachung ChenAbstract:An Infrared Thermometer can be used to detect the temperature of materials not in-contact, in situ and in real-time measurement. The set emissivity is key to obtaining the accurate measurement. In this study, we investigated a novel technique to determine the emissivity and temperature of construction materials by using an Infrared Thermometer and two contact Thermometers. These measured values were transformed into true temperatures by calibration equations to improve their measurement accuracy, then the emissivity and temperature of the materials were determined by regression analysis. The mean emissivity of seven materials was 0.937, 0.942, 0.944, 0.804, 0.802, 0.902 and 0.911 for black plastic, polyethylene plate, red brick, paper, cotton cloth, wood and flat glass, respectively. The range of emissivity we determined was similar to that in the literature. The precision of the measurement is acceptable for practical application. The method we developed is easy and inexpensive and could be used for other materials.

The temperature measurement of infusion fluid by Infrared Thermometer is useful for safety in infusion therapy
Masui. The Japanese journal of anesthesiology, 2003Co-Authors: Kenji Ohki, Yuka Yamamoto, Takashi Matsukawa, Toru Gouhara, Yumiko Matsuzaki, Takao OshibuchiAbstract:BACKGROUND: The measurement of infusion fluid temperature is important for patients' thermoregulatory management. However, we usually estimate the temperature by touching and feeling the surface of the infusion bag. Accordingly, there is increasing demand for more quantitative method to measure infusion fluid temperature. METHODS: In the operating room we evaluated the accuracy and precision of the Infrared Thermometer (Genius) for the measurement of infusion fluid temperature compared with the thermistor. RESULTS: The fluid temperature measured by Genius is accurate with sufficient precision compared with that measured by thermistor. CONCLUSIONS: The temperature measurement of infusion fluid by Infrared Thermometer is clinically helpful and useful for patients' safety.

research and realization of convergence between Infrared temperature measurement technology and video surveillance system of substation
Power system technology, 2008Co-Authors: Li RanAbstract:Firstly,according to Infrared theory a temperature measurement model and a temperature modification model are constructed.Then,in the light of actual demand of power system,the performance index of Infrared Thermometer is decided and based on the proposed models the temperature measurement results are modified,thus the accuracy of temperature measurement is improved.Finally,the implementation scheme of hardware and software for concrete video surveillance system are given,and the secondary development of original video surveillance system is conducted to realize the selection of power equipments whose temperatures are to be measured by use of the surveillance picture as well as to control the action of Infrared Thermometer installed in substation.The proposed video surveillance system is low cost and simple to realize,and possesses some practical value in engineering.
