Low Blood Sugar ‘Sniffer’

Sensors are the lifeblood of the Apple Watch’s health and safety tracking, but Apple is looking beyond the heart sensor. While the company is thought to be developing some type of noninvasive glucose monitor, it patented a unique technology last year that could potentially “smell” blood sugar levels.

Essentially, that sensor would be an environmental air sensor that could sniff out certain chemicals in the air. While that system could detect spoiled food or body odor, as well as potential environmental hazards, it could also theoretically “smell” a user’s sweat and determine if their blood sugar is low.
