Optical sensor solution for wearables is industry's thinnest
Maxim Integrated Products has introduced what it claims is the thinnest optical sensor solution for wearable health and fitness products.

The MAXM86146 dual-photodetector optical sensor solution is a turnkey drop-in module that 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, says the company, enable innovative biosensing features in less space and support the rapid development of accurate, continuous health-monitoring devices.

"Design space and time-to-market are at a premium for designers of next-generation wearable healthcare monitors," says Andrew Baker, managing director, Industrial and Healthcare Business Unit at Maxim Integrated. "With the world's thinnest dual-photodetector optical sensor solution, we enable greater capacity for designers to rapidly introduce innovative capabilities."

The MAXM86146, says the company, enables designers of advanced wearable products to achieve a 45 percent thinner optical design versus a discrete approach. In addition, the module is offered as providing ready-to-use biosensing algorithms that measure vital signs to the most rigorous medical standards, saving designers up to six months in bringing new products to market and providing extra time and space to expand functionality.

Key benefits of the MAXM86146 are offered as the following:

  • Smallest Size: Provides the world's thinnest dual-photodetector optical sensor solution to enable lighter, more compact power-efficient devices; Combines two photodiodes, an optical analog front end (AFE) and a microcontroller with built-in algorithms (activity classification, heart rate, SpO2) in a 0.88-mm package that is 45 percent thinner versus a discrete approach.
  • Faster Time-to-Market: Drop-in module solution cuts development time by up to six months.
  • Innovation Focus: With ready-to-go algorithms that measure key vital signs, developers can focus on expanding functionality instead of algorithm development.

The MAXM86146CFU+ is available for $5.84 (1000-up, FOB USA). An evaluation kit - the MAXM86146EVSYS - is available for $150.
