Google reveals Pixel 8 Pro phone thermometer feature, accurate to ±0.3°C

According to news on January 28, Google has brought a practical upgrade to Pixel 8 Pro in the latest Pixel feature update - the infrared sensor has been transformed into a smart thermometer, allowing users to easily measure body temperature without contact.

Pixel 8 Pro’s infrared sensor was originally used to measure the temperature of objects, but now it has expanded its functionality to provide users with a convenient, accurate and hygienic way to measure body temperature. Pixel 8 Pro’s body temperature sensor is located near the rear camera, allowing users to measure their temperature by scanning the temporal artery simply by swiping the phone across their forehead. Google believes this method is more accurate than traditional forehead thermometers, providing a temperature measurement range of 36.1°C – 40°C with an accuracy of up to ±0.3°C. Clinical trials have also proven the accuracy of this feature, comparing favorably to FDA-cleared temporal artery thermometers. In order to improve the user experience, Pixel 8 Pro also adds an LDAF laser autofocus sensor, which will detect the distance between the phone and the forehead before measurement begins to ensure the best position for accurate readings. In addition, tactile feedback and voice commands will guide users through the entire process, making it more convenient and easier to use. Pixel 8 Pro’s infrared sensor has a field of view of over 130 degrees, but in order to get accurate readings, the phone needs to be within 0.5 inches (note: about 12.7 mm) of the skin. It is worth mentioning that this non-contact measurement method can also effectively prevent the spread of bacteria. Google conducted a strict FDA De Novo classification process for the thermometer function to ensure that it meets the standards of a medical device. The program includes a clinical validation study involving a large number of participants, focusing on accuracy, safety and ease of use. Obtaining FDA certification not only emphasizes the reliability of the thermometer, but also highlights the advantage that it can operate without an Internet connection, allowing users to use their mobile phones to measure body temperature anytime and anywhere, even if they do not have other thermometers.
