Researchers develop an application 'FeverPhone' that allows smartphones to be used instead of thermometers
Researchers at the University of Washington have developed an app called FeverPhone that lets you use your smartphone as a thermometer. Smartphones are equipped with sensors that detect temperature, but this is only used for internal temperature monitoring, and 'FeverPhone' is an application that uses the touch screen.

Fever is known to be a common symptom of COVID-19, but when you want to take your temperature, you may not be able to find a thermometer. Even if you think 'I can buy it if I need it', it is often the case that other people need a thermometer and cannot get it immediately.
Researchers at the University of Washington have developed an app called 'FeverPhone' that can measure body temperature without acquiring new hardware to address these issues.
'FeverPhone' uses the smartphone's capacitive touch screen and the temperature sensor used to monitor the temperature of the internal module inside the terminal, and collects data for estimating the deep temperature with a machine learning model.
To use, press the touchscreen of your smartphone against your forehead for about 90 seconds.
When researchers tried 'FeverPhone' on 37 patients and compared the body temperature estimate with the measured temperature of the oral thermometer, the average error was 0.23 ° C. Of the 37 people tested, 16 had at least mild fever.
None of the test participants had a fever of 38.6°C or higher. This is because if you have a high fever, you can easily see that you are 'heating', and if you are sweating, you may not be able to obtain correct measurement results with a skin-contact thermometer.

Dr. Mustafa Springston, a co-author of the paper and a clinical lecturer at the University of California School of Medicine, said, ``People often come to the ER (emergency department) and say, ``I feel like I have a fever,'' but ``I have a fever.'' It's a whole different story: A flu pandemic can take five days, or even a week, to rush to the ER, and if people can share their fever status with public health agencies through an app, early signs can be dealt with that much sooner. It may help,' he said.
The research team is subsequently working on whether smartwatches can do the same.
