The VSee telehealth and telemedicine solution for the Vuzix M300XL and Vuzix Blade Smart Glasses is expected to be commercially available during Q2 2019.
Such technology would enable owners of future iPhones and Apple Watches to detect things like spoiled food, body odor and perhaps even blood sugar levels.
Also announced were six Alexa healthcare skills from leading healthcare providers, payors, pharmacy benefit managers and digital health coaching companies.
Part of the watchOS 5.2 update, the ECG app can capture heart rhythm in a moment when users experience symptoms such as a rapid or skipped heart beat.
The solution proved in clinics to create a time reduction and ease of use unparalleled by other documentation solutions.
The market is expected to reach 279 million units by the end of 2023 with a compound annual growth rate (CAGR) of 8.9%.
Much of the growth was attributed to the growing number of ear-worn devices as they captured almost a quarter of the market during the year.
New devices include Fitbit Versa Lite Edition smartwatch, and a trio of activity trackers - Fitbit Inspire HR, Fitbit Inspire and child-friendly Fitbit Ace 2.
The Clinical Trials Bot lets patients and doctors search for studies related to a disease and then answer a succession of text questions.
The story ends on May 31 when web-connected services won't work any more; Band owners will still be able to track their fitness activities, though.
