Analog Devices MEMS technology used in Withings Pulse Activity Tracker

Analog Devices, a supplier of high-performance semiconductors for signal processing applications, has revealed that its ADXL362 MEMS accelerometer has been integrated into the Pulse activity tracker developed by Withings, a company that creates smart products and apps to help people take care of their health and well-being.

The Pulse activity tracker is a pocket-sized tool designed to help users to achieve their personal health and fitness goals and it offers a range of monitoring features, from tracking the number of steps and the distance travelled, to calculating the number of calories burned, measuring heart rate and detecting the quality of sleep.

Withings needed technology that was bale to combine a high-performance solution with ultra-low power consumption for a longer battery life and enhanced user autonomy.

The 3-axis, ADXL362 MEMS digital accelerometer consumes less than 2 µA at a 100-Hz output data rate and 270 nA when in slower sampling wake-up mode. The MEMS accelerometer includes an activity detection function that distinguishes between different kinds of motion and prevents the sensor from turning the system on unnecessarily and using additional battery life.

“The Withings Pulse activity tracker lets you understand and analyse your fitness, and that’s the first step to improving it. The quality of Analog Devices’ MEMS motion sensing technology that we’ve managed to fit into this tiny device and the exceptional battery life it provides makes it the perfect companion for a healthy lifestyle,” said Eric Carreel, president and co-founder of Withings.
