More Than Body Fat: Samsung Galaxy Watch Patent Could Monitor Abdominal Fat

AI summary

Samsung has been granted a Galaxy Watch patent for estimating abdominal subcutaneous and visceral fat by combining data from multiple sensors, a method the patent says reduces measurement complexity while improving accuracy and speed. The approach would add ultra-wideband (UWB) radar to the watch, sending signals toward the abdomen and reading the reflected waves, then combining that with existing bioelectrical impedance (BIA) data and basic details such as weight, height, age and sex to estimate abdominal fat area and visceral fat levels.

More Than Body Fat Measurement: New Samsung Galaxy Watch Smartwatch Patent Can Monitor Abdominal Fat

IT之家, November 13 — According to the list published by the United States Patent and Trademark Office (USPTO) on November 3, Samsung has been granted a patent for a Galaxy Watch smartwatch that, by combining data from multiple sensors, can detect the wearer's "visceral fat."

The patent, titled "Abdominal Fat Estimation Method and System," describes a technical solution for assessing abdominal subcutaneous fat and visceral fat on a portable device. The patent states that this approach can reduce measurement complexity and improve the accuracy and speed of estimation.

Unlike ordinary body fat percentage, this technology focuses on "visceral fat." Subcutaneous fat lies beneath the skin, while visceral fat mainly wraps around the organs in the abdominal cavity and usually requires clinical imaging equipment such as MRI or CT for relatively accurate measurement; although some smart body fat scales can give estimated values, their accuracy is limited.

Samsung's patent plans to introduce ultra-wideband (UWB) radar into the watch. The device would emit signals toward the abdominal area and receive the reflected waves, then combine them with the bioelectrical impedance (BIA) data already available on the Galaxy Watch, as well as basic information such as weight, height, age, and sex, to comprehensively calculate abdominal fat area and visceral fat level. IT之家 attaches the relevant patent diagrams below:

Samsung has equipped BIA sensors since the Galaxy Watch 4, capable of measuring indicators such as body fat percentage, skeletal muscle mass, and BMI. If the new patented technology is implemented, the UWB sensor would become a key new piece of hardware and could also become an important health upgrade for the next generation of Galaxy Watch.
