De Novo OK for Google Phone Thermometer
FDA has granted a de novo marketing authorization to Google and its new body temperature app on its latest Pixel 8 Pro smart phone. The app is part of the company’s January Pixel feature drop and it allows users to quickly scan a person’s forehead with the phone to measure the body temperature. “In clinical trials, our software algorithm was able to calculate body temperature in the range of 96.9°F - 104°F (36.1°C - 40°C) to within 0.3°C when compared with an FDA-cleared temporal artery thermometer,” the company says.
“Bodies emit infrared radiation — or, simply put, heat,” Google says. “The Pixel 8 Pro team added an infrared sensor to the phone next to the rear camera, which at launch was used to power the object temperature feature and now powers the body temperature feature as well. Measuring body temperature on the Pixel 8 Pro is simple: Just point the rear camera at the forehead and sweep across. The Pixel 8 Pro body temperature app accurately measures your temperature by scanning the temporal artery, unlike less accurate forehead thermometers that are pointed at the center of the forehead. The data from the infrared sensor is passed to an algorithm to calculate the temperature that will be displayed on your device, powered by the Tensor G3 chip.”
