Taking your body temperature is one of the few things you can’t yet do with your smartphone, but that could soon be set to change. A team of US researchers has developed an application that turns your phone into a tool for detecting whether or not you're running a fever.

These days, you're much more likely to have a smartphone to hand than a thermometer. With this in mind, researchers from the University of Washington have come up with FeverPhone, an application that can turn a smartphone into a thermometer, without the need for additional hardware. It actually uses the phone's touchscreen and battery temperature sensors to collect data, which a machine learning model then uses to estimate body temperature.
