South Korean tech giant Samsung Galaxy Watch is likely to add a body composition monitor that could give consumers a better understanding of their overall health.
Sensors measure the user’s body composition, including the ratio of body fat to muscle. According to Max Weinbach, the Samsung Galaxy Watch 4 will include a bioelectrical impedance analysis (BIA) sensor, a feature often found on smart scales.
BIA is a method for measuring the composition or percentage of fat in muscles and other tissues in the human body, according to an Android Authority report. The sensor detects low voltage impedance or interference sent through the body.
The BIA uses this data to assess whether a user is too weak or obese because bone, muscle, fat, and other tissues have different electrical resistance properties.
According to Doylestown Health, current BIA sensors typically use two electrodes placed on the patient’s opposite arm and leg, the report said.
Samsung can get around this by asking the user to touch the watch with the other hand to close the circuit. A patent filed in 2019 (h/t Patently Apple) suggests Samsung is likely to use this solution.
Wearable BIA measurements can be a valuable addition for those looking to build muscle, monitor their overall health, or burn fat. It also syncs efficiently with other performance metrics like VO2 Max.
While the Galaxy Watch 3 isn’t the most effective fitness tracking medium, Samsung seems to be improving that aspect of the wearable. Samsung is expected to introduce the Galaxy Watch 4 and Galaxy Watch 4 Active on June 28.
