More lifestyle coaching than mere wearable devices, Cloudtag has launched its Cloudtag Track frictionless, wearable device, developed in collaboration with imec, the nanoelectronics research centre.
The fitness tracker combines fitness and health monitoring with design, it says, for fitness and the care, cure and prevention cycle by providing immediate access to medical data and personalised feedback.
imec developed algorithms for the medical technology company’s wearable sensor devices that enable accurate monitoring of physiological parameters. Cloudtag Track is its first wearable multi-sensor device. It is light and small, yet integrates a proprietary algorithm that retrieves physiological parameters with what the company claims is “an exceptionally high level of accuracy”. The algorithm recognises activity, measures energy expenditure, heart rate and other physiological data.

Power management chip extends battery and shelf life
Designers can optimise power and battery life for wearable medical/fitness and IoT applications, using the MAX14720 PMIC, says Maxim Integrated. It can be used for non-rechargeable battery (coin cell, dual alkaline) applications where size and energy efficiency are critical. An electronic battery seal also extends shelf life by effectively disconnecting the battery prior to initial power-up.
It also reduces bill of materials with the functionality of five discrete devices – power switch, linear regulator, buck regulator, buck-boost regulator, and monitor, says the company.
Heart rate monitoring sensor lowers cost of heart rate measurement
Designed to reduce the cost and complexity of wrist-based heart rate monitoring (HRM) applications, the Si1144 has a low-power optical sensor module, paired with an EFM32 Gecko microcontroller running the company’s HRM algorithm.
GPS/GLONASS receiver is sensitive for low power devices
Suitable for power-sensitive applications, such as wearable devices, the u-blox 8 GPS/GLONASS receiver addresses power sensitive usage.
Compared with the earlier u-blox 7, it has increased tracking sensitivity, increased by 4dBm to -166 dBm. The enhanced odometer functionality, a new geofencing feature, and optimised pre-set power save modes can halve the power requirements for sport products, says the company.
AssistNow boosts GNSS acquisition performance, available online, offline or as an autonomous service. Positioning makes it suitable for all battery powered devices, especially wearables and sports tracking.
u blox 8 is pin-compatible with u blox 7. It will be available as a chip and as modules in several form factors. Customer samples will be available by Q2 2016.
