How Samsung Watches Measure Body Fat
Samsung uses several sophisticated technologies to measure body fat through its smartwatches. The primary method employed is bioelectrical impedance analysis (BIA). This technology has become prevalent due to its accuracy and ease of use in consumer-grade devices.
What is Bioelectrical Impedance Analysis (BIA)?
BIA works on a simple principle: when a small electrical current is passed through the body, it encounters resistance (impedance) from various tissues. Different tissues—such as muscle, fat, and bone—conduct electrical currents differently.
- Muscle contains a high amount of water and is a good conductor, leading to low resistance.
- Fat, on the other hand, has a lower water content and higher resistance.
By measuring the resistance encountered by the electrical signal, the smartwatch can estimate the user’s body composition, including body fat percentage.
How Samsung Implements BIA
Samsung smartwatches, such as the Galaxy Watch 3 and Galaxy Watch Active2, are equipped with all the necessary sensors to perform BIA. The process usually involves the following steps:
Electrode Placement: Samsung watches have metallic electrodes built into the case. When a user initiates a body fat measurement, they typically need to touch the watch’s bezel with their fingers, effectively completing the electrical circuit.
Electrical Current Delivery: The smartwatch sends a mild, safe electrical current through the body.
Impedance Measurement: The watch measures how much the current is impeded as it travels through the user’s body.
Data Analysis: The internal algorithms convert the impedance data into an estimate of body fat percentage, along with other metrics like muscle mass, body water percentage, and basal metabolic rate (BMR).
