Unlike existing devices that require additional sensors, FeverPhone uses components called thermistors already built into the smartphone to monitor the thermal energy between the device and the user.
The researchers tested the app on 37 participants, including those with a mild fever. They then compared the results with conventional thermometers.
FeverPhone was able to predict body temperature with an average error of about 0.23°C; this is consistent with the accuracy of household thermometers, including non-contact options.
Researchers are currently working to improve the app’s accuracy and expand its compatibility with various smartphone models.
