The Galaxy Watch7's BioActive Sensor stands out due to its advanced design and enhanced capabilities, which significantly improve health monitoring features compared to previous models. Here are the key aspects that make it unique:
Enhanced LED Array
The new BioActive Sensor incorporates a wider array of LED colors, including Blue, Yellow, Violet, and Ultraviolet, in addition to the traditional Green, Red, and Infrared LEDs. This expansion allows for more accurate readings across various health metrics such as heart rate, blood oxygen levels, and sleep quality. The addition of these colors helps isolate signals better and improves accuracy during workouts where movement can affect readings[1][2][3].Improved Photodiode Performance
Samsung has doubled the performance of the light-receiving photodiodes while halving their number. This redesign not only optimizes space on the chip but also enhances the sensor's ability to capture light accurately. As a result, users can expect up to 30% more accuracy in tracking heart rate and blood oxygen levels compared to earlier models like the Galaxy Watch6[1][2][3].Advanced Health Metrics
One of the standout features enabled by this sensor is the Advanced Glycation End Products (AGEs) Index, which provides insights into metabolic health and biological aging. This index is influenced by lifestyle and dietary habits and serves as a marker for overall health. By monitoring AGEs, users can gain a better understanding of their biological age and make informed decisions regarding their health[1][3][5].Integration of Multiple Sensors
The BioActive Sensor operates as a 3-in-1 chip, combining an optical heart rate monitor, electrical heart signal tracking, and bioelectric impedance analysis. This integration allows for comprehensive tracking of various health indicators within a single device, streamlining the user experience[2][4].In summary, the Galaxy Watch7's BioActive Sensor introduces significant advancements in health tracking technology through improved LED capabilities, enhanced photodiode performance, and new health metrics that provide deeper insights into users' wellness.
