A thermometer built into your laptop? Researchers at the University of Washington in the United States claim to have developed an application that allows this, reports the specialized media Gizmodo. Called the FeverPhone, it enables an accurate temperature reading by pressing the screen against a person’s forehead for 90 seconds.
Tested on 37 participants in the Washington University School of Medicine emergency department, including 16 who had mild fever, it predicted their body temperature with an average error of about 0.23 degrees Celsius, which corresponds to the accuracy of thermometers used at home. .
heat exchange
Modern mobile phones already measure the heat of their components such as the battery, in order to activate possible safety measures to prevent overheating. Your iPhone lets you know if it needs to cool down to make it safe to use.
The sensors are integrated into the smartphone, and are also used in medical thermometers, they cannot directly measure the body temperature after the inside of a smartphone, but the amount of hair is transferred between a user and the mobile appareil with the touch of the phone between them. contact.
To simulate a feverish subject, the researchers used a vacuum machine to heat a bag filled with water and pressed it against the screens of different phones. The sensor was then used to measure how fast the device was heating up, and this data was used to train a learning model that allows the FeverPhone app to make its estimates.
easy to use solution
Connected objects like the Apple Watch Series 8 and Apple Watch already allowed a user’s temperature to be measured using built-in sensors. However, Apple warned that this technology was not worth a real medical diagnosis, but simply provided an analysis of its user’s sleep stages. Unlike taking heart rate, the Apple Watch also doesn’t allow for on-demand temperature readings.
While taking your temperature is always crucial in the post-pandemic period, FeverPhone lets you do it this time without any external equipment or dedicated software.
