Maxim Integrated introduced two sensors for health and fitness that require lower power to monitor temperature and heart rate.
The MAXM86161 in-ear heart-rate monitor takes up 40% less space for continuous heart and Sp02 measurements. It is designed to help product developers cover a wide range of use cases, both in-ear and elsewhere.
The MAXM86161 consumes 35% lower power than competing products to expand battery life and has an integrated analog front end, to eliminate the need for procuring a separate chip to connect to an optical module.
It measures 2.9 x 4.3 x 1.4 mm, making it 40% smaller than the closest competitor. It sells for $4.41 and an evaluation kit is available for $150.
The other sensor is the MAX30208 digital temperature sensor, designed to deliver clinical-grade temperature measurement accuracy (plus or minus 1 degree Centigrade) with fast response time to changes in temperature. It can be used for battery-powered applications for smartwatches and medical patches. Also, It can be attached to either a PCB or a flex-printed circuit.
MAX30208 is available in a 10-pin thin size, measuring 2 x 2 x 0.75 mm for $1.25. An evaluation kit is available for $56.
Wearables will account for $56 billion in revenues globally in 2019, rising to $78 billion by 2022, according to IDTechEx Research. Growth will come from smartwatches and ear-worn products, as well as healthcare devices dedicated to specific measurements.
