The MAXM86146 dual-photodetector optical sensor from Maxim Integrated is the thinnest optical sensor for health and fitness wearables. Designed to fit into places where they never used to fit, the turnkey drop-in module includes built-in algorithms for heart-rate and oxygen-saturation (SpO2) monitoring, as well as advanced activity classification. Its small size and ease of design enable innovative biosensing features in less space and support the rapid development of accurate, continuous health-monitoring devices.

“By cutting our development time, Maxim Integrated’s state-of-the-art optical sensor solution enabled us to leap-frog the competition by allowing us to focus on new feature introductions,” said Satish Movva, founder and CEO of CarePredict. “In addition, caregivers got unprecedented remote access to the activity and behavior indicators of seniors through the CarePredict wearable to help manage their health conditions from afar.”

The MAXM86146 offers designers of advanced wearable products the ability to achieve a 45% thinner optical design versus a discrete approach. Additionally, the module offers ready-to-use biosensing algorithms that measure vital signs to the most rigorous medical standards, allowing even more time to develop market-differentiating features. It saves designers up to six months in bringing new products to market and provides extra time and space to expand functionality, says a press release.

The revolution in wearable health monitors is gaining momentum as it provides unprecedented access to health insights that help medical professionals and end-users proactively manage preventative care needs and chronic conditions. Developers strive to continue this momentum by creating innovative solutions to provide deeper insight into health conditions and open doors to improve wellness.
