Health Management Sensor

PixArt's Health Management product line, which utilizes the PPG (Photoplethysmography) technology, is a cluster of highly integrated modules designed for non-invasive health management applications. Unlike a conventional photodiode detector that only outputs basic PPG readings such as heart rate detection and heart rate variability (HRV), an image-based PPG product can further interpret the PPG signals to attain even more personalized health information.

PixArt's PPG sensor products offer robust platforms that help to realize a wide range of physiological detection functions on wearable, hearable and portable devices. With the appropriate system development, they can make health/fitness-related applications possible by delivering informative data such as the heart rate detection values (incl. stationery-, sport- or Wear OS-compliant grades), stress-level tracking (via HRV SDNN value), respiratory monitoring, cardiopulmonary quality tracking, sleep-related breathing assessment, and irregular heartbeat screening. 

With our extensive knowledge and experience in supporting customers' development cycles, a wide range of operating scenarios in real-life situations have been carefully considered throughout sensor design. This is why our PPG sensors are built with efficient processing ability right from the hardware level. Power built-ins such as Auto-Gain Control (AGC), Auto-Exposure Control (AEC), Auto LED Control, ambient interference suppression, skin tone coverage support, and hair-density stabilization can be found in PixArt's PPG products for a consistent bio-sensing coverage rate. All PixArt's PPG products also share several common architectural features, including low power consumption, small form factor, auto-adjusting mechanisms, and anti-ambient interference. Nevertheless, references to optical-mechanical designs are also available that allow you to train your own algorithms for complete flexibility.
