Samsung brings major improvements to the Galaxy Watch7 thanks to the new BioActive sensor

The South Korean firm presents in advance its new BioActive sensor, which arrives at the Galaxy Watch7 with better photodiodes and more accurate data collection that will allow health monitoring of another category

For some time now, the giant Samsung has been a pioneer when it comes to promoting innovation in digital health, and in fact since the times of that original ‘Samsung Simband’ that remained a prototype, its health sensors have not stopped evolving and improving to achieve that long-awaited simplification of health monitoring. well-being and rest as well as sports quantification by users.

And in this situation of continuous improvements, Samsung is preparing the landing of its first Galaxy Ring ring with quantification sensors, in addition to a new generation of Galaxy Watch that we will see at Unpacked and that, this time, it seems that they will offer a very important generational leap.

Not surprisingly, Samsung has already presented in advance the Exynos W1000 chip with 3-nanometer lithography that will electronically animate these new smartwatches, while today this effort is focused on presenting us with simple and more accurate health tracking than ever through its BioActive sensor, which promises advanced wellness prediction and prevention functions according to the official press release published by Samsung.

This is how the Galaxy Watch7 will improve thanks to Samsung’s new BioActive sensor

The new BioActive sensor is essential to provide the best preventive health experiences in the new Galaxy Watch7, finally offering that qualitative leap that we have been waiting for a long time. This is how Samsung engineers have made three key improvements to the sensor: increasing the performance of the photodiodesadding more light-emitting diode (LED) colors, and optimally distributing them throughout the sensor.

Samsung explains that the performance of each photodiode has more than doubled, reducing from eight to four the number of LEDs needed to maintain the current measurement capacity. This redesign saves energy and frees up additional space to integrate new LEDs of different colors with different functions, while also ensuring optimal placement throughout the sensor. In fact, this new BioActive sensor that Samsung presents includes blue, yellow, violet and ultraviolet LEDs for the first time, as well as a greater number of green, red and infrared LEDs.

All this in favor of an optimal measurement of health parameters that, with this integration and disposition, will allow Samsung to take innovation a step further and explore new parameters of health monitoring and quantification in wearables.

More precision, new possibilities for preventive well-being and AGE measurement

These new photodiode arrangements and colours will provide reliable accuracy of all health parameters, including heart rate, sleep quality, blood pressure, blood oxygen levels and stress levels, which are now monitored more accurately. Samsung promises that even in intensive training, the heart monitor will be 30% more accurate compared to its predecessor, something that the most advanced athletes have been asking for a long time to eliminate gadgets from their equipment and precision heart rate monitors.

Now, Galaxy Watch7 opens up new possibilities, allowing you to better predict trends and take proactive steps for preventive care. The most important of these new features will be the implementation of the Advanced Glycation End Product Index (AGE) monitor, an indicator of metabolic health and biological aging heavily influenced by lifestyle and dietary habits. Used as a biomarker, this index provides a snapshot of the user’s biological age, helping them make better decisions on their wellness journey.

The addition of the AGEs index is just one of the many advanced features planned for the Galaxy Watch7, and that’s how Samsung’s seventh wearable iteration will bring more sophisticated and smarter health and wellness tools to help users achieve their goals, take better care of themselves, rest better and do it all in a simple way and carry only one device.
