Samsung Galaxy Watch 4 Might Come with BIA Sensor to Measure Body Fat Composition

The BIA (bioelectrical impedance analysis) sensor could be the first on any mainstream smartwatch.


Samsung is rumoured to host a new event on August 3, 2021. The company is expected to announce new foldable smartphones like the Z Fold 3 and Z Flip 3. Rumours are rife that the company will also introduce new wearables at the Unpacked event. If reports are to be believed, we might see a new Galaxy Watch at the upcoming Samsung event. Samsung has not made any official confirmation or announcement about the rumoured event. Meanwhile, some key details of this rumoured smartwatch have surfaced online. According to a new tip from Max Weinbach, the upcoming Samsung Galaxy Watch 4 will feature a new BIA sensor. 

The BIA (bioelectrical impedance analysis) sensor could be the first on any mainstream smartwatch. The sensor is commonly found on smart scales and is used to measure body fat composition. The sensor reads impedance, or disruption, of a low voltage current sent through the body. The BIA, then, uses this data to estimate whether the user is lean or obese based on the different electrical resistance qualities that bones, muscle, and fat have.

The Samsung Galaxy Watch 4 will also feature other sensors for heart rate monitoring, stress monitoring, etc. It was previously rumoured to ditch non-invasive blood sugar measuring sensors. Samsung will launch the Watch 4 in two screen sizes – 42mm and 46mm – according to reports. As per a recent Safety Korea listing, the Watch 4 with a 42mm screen will have a 240 mAh battery. 

The company is also likely to launch an Active version of the Watch 4. It will have 40mm and 42mm screen options. Tipster Ice Universe had previously claimed that the two smartwatches will run on Android instead of Tizen. The Watch 4 has already passed the FCC website, hinting at an imminent launch. It is likely to come in Wi-Fi and Wi-Fi + LTE options. What are your thoughts on the upcoming Samsung smartwatches? Do let us know in the comments below.
