activity tracking wearables

The WHOOP 4.0 works with WHOOP Body, allowing users to wear the sensor in exercise gear or sleepwear.

Manal Almalki, PhD, of Jazan University in Saudi Arabia, is empowering patients to monitor their health at home so they can gain insights into their own body using wearables; the tool is also aggregating data during the patient-run experiments.

When monitoring heart rate, skin temperatures, activity and other physiological data, biometric-sensing wearables are also tracking important indications of abnormality associated with infection, inflammation or even insulin.

Some 21 percent of US adults use a wearable device right now, and of those, 36 percent use a Fitbit device, according to a Forrester Research survey of 952 online US adults.

In February Fitbit announced a voluntary recall of its newest activity tracking device, the Fitbit Force, after a number of users complained of skin irritation from the wristworn device.

Misfit Wearables, the company behind the Misfit Shine activity tracker, has upped its sleep tracking game, entering into a partnership with Beddit, the Helsinki, Finland-based mattress sensor startup.

In the first quarter of 2014, Fitbit held the majority of the market share, according to a report from Canalys.
