The United States Patent and Trademark Office published a Samsung patent on November 3, detailing a method for estimating abdominal fat using a Galaxy Watch. The technology focuses on measuring visceral fat, which surrounds internal organs, rather than just subcutaneous fat.
The proposed system utilizes ultra-wideband radar technology to send and receive signals from the abdominal area. This data is combined with existing bioelectrical impedance analysis metrics, along with user information such as weight, height, age, and gender, to calculate fat levels.
Samsung has included bioelectrical impedance sensors in its smartwatches since the Galaxy Watch 4 series. The integration of ultra-wideband radar represents a potential hardware upgrade for future wearable devices to improve the accuracy of health monitoring.
