Wireless determination of skin temperatue by an infrared camera compared with I-buttons measurements

In field studies measurements of skin temperatures are often complicated because of the use of wired sensors. There for iButtons, a self-sufficient systems that measures temperature and stores the data in a protected memory section, are quite popular. Due to de velopment of infrared measurements there is now an alternatieve. The study deals with comparison between the infrared camera measurements and those of the iButton and its application on the human skin, and describes measurements in a laboratory setting. Real-time measurements of upper-extremity skin temperature were performed in a controlled and conditioned room by an infrared camera. Mean skin temperature was measured continuously at 1 min intervals by iButton sensors and compared with those by the infrared camera. These results were compared and related to findings from literature. In conclusion, the application of infrared camera measurements is advantageous for measuring skin temperatures in those situations in which wired instruments are unpractical and fast responses are required and also they the advantages of faster responds which might be helpful for controlling the human comfort based on skin temperature.
