Withings, a Paris-based company known for its innovative line of WiFi-connected health devices, has embedded ADI’s ADXL362 MEMS accelerometer in its Pulse activity tracker.
This has enabled it to measure more than steps, distance, climbing elevation and calories burned. The new Withings Pulse O2 can display blood oxygen levels that help monitor sleep quality and heart rate. This data is automatically downloaded to the user’s computer, tablet or smartphone.
“The Withings Pulse activity tracker lets you understand your fitness, and that’s the first step to improving it,” said Éric Carreel, Chairman of Withings, which has won several design and consumer electronics awards.
Finding the right accelerometer for a tracker as small as the Pulse—which fits in a pocket and can be attached to a wristband—posed a serious challenge for Withings’ designers. But at 3.00mm x 3.25, ADI’s ADXL362 proved to be the perfect (and perfectly sized) solution.
The accelerometer includes an enhanced activity detection function that distinguishes between different kinds of motion. And because the ADXL362 operates on ultra-low power, it enables the Pulse to last one to two weeks before needing to recharge.
“The quality of the technology and the exceptional battery life in this tiny device makes it the perfect companion for a healthy lifestyle,” said Carreel. Several ADI components are under consideration for the company’s next smart product.
“Today, when you ask people who takes care of their health, the first response is ‘my doctor.’ Tomorrow, with these tools, their reply will be, ‘I take care of my health.’ The patient-doctor relationship will change. With a dashboard, their health will be obvious,” said Cédric Hutchings, CEO of Withings.
Though the market is glutted with pedometers, few offer the features of the Pulse O2. To measure your heart rate, you simply hold a finger to the sensor for an instant reading, which then synchs with an Android or iOS device via Bluetooth 4.0.
The magical ease of that feature prompted one reviewer to call it “witchcraft!”
