AIRO, a startup based in Kitchener-Waterloo, Canada has developed a wrist sensor that can track nutrition, stress, sleep and exercise. Medgadget has recently covered a number of wrist sensors, but this is the first with claims that it can track nutrition by using optical spectroscopy. The wrist sensor projects light from an LED into the bloodstream to detect metabolytes associated with food intake based on their optical signatures and can supposedly distinguish between carbohydrates, fats and proteins.
AIRO tracks stress levels by monitoring the heart rate variability, but is not able to warn the user if the stress levels rise significantly. The company also claims device is able to learn over time what calms the user and what does not. Similar to the FItbit and Nike Fuelband SE activity monitors, AIRO tracks sleep cycles, can measure the percentage of restful sleep and is able to wake the user at an optimum time. Lastly, AIRO is able to track exercise activity and calories burned by monitoring the pulse rate and how the device is moving throughout the day.
AIRO is available for a pre-order price of $149 and is promised to be shipped in the fall of 2014.
