PulseOn+ STMicroelectronics: Pushing the smallest and most accurate wearable heart rate monitor

Recently, STMicroelectronics (ST), a leading global semiconductor supplier across multiple electronic applications, announced that its miniature motion sensing and data processing chip has been adopted by PulseOn for the development of the smallest and most accurate on the market. Wearable heart rate monitors allow sports and fitness enthusiasts to control their heart rate anytime, anywhere.

This slim, stylish bracelet heart rate monitor features an intuitive interface design that makes it easy to measure heart rate accurately and continuously without the need for a heart rate belt or chest strap. Complex algorithms can convert heart rate data into meaningful ones based on demand. Personalized information.

Numerous scientific experiments have demonstrated that ST's low-power, high-performance MEMS accelerometers maintain the accuracy and reliability of PulseOn heart rate measurements in a variety of possible situations, from no body movements to intense cardiac loads. The same level as the electrocardiograph.

ST's advanced accelerometers effectively track arm movement and vibration, completely solving the noise problem in optical blood-flow detection. Therefore, the PulseOn heart rate monitor can distinguish between the actual heart rate pulse signal and the noise signal generated by the arm movement. In addition, the accelerometer can also determine the amount of motion of the user.

The STM32L microcontroller ensures that each unit operates at its lowest power consumption. PulseOn developers perfectly leverage the STM32L's flexible ultra-low power modes and optimize the power consumption of the heart rate monitor, allowing the microcontroller to perform tasks with minimal power consumption at all times.

Benedetto Vigna, executive vice president and general manager of analog devices, MEMS and sensors products at STMicroelectronics, said: "This sophisticated, stylish electronic device will monitor the user's heart and significantly improve their quality of life. PulseOn uses our sensors And controller chips prove that STMicroelectronics plays an important role in developing innovative and easy-to-use medical fitness products."

Jari Nousiainen, director of engineering at PulseOn, said: "The STMicroelectronics chip with excellent accuracy and performance allows us to import the most stringent scientific standards into PulseOn heart rate monitoring technology to achieve reliable results, including heartbeat to heartbeat during breaks (beat-to -beat) Measurement accuracy, and just as important, the tiny size and low power consumption of STMicroelectronics chips is also a competitive advantage, helping us to develop the smallest and most accurate wristband heart rate monitor on the market."
