Wearable technology is moving beyond consumer-grade health and wellness devices – the daily step counters and heart rate trackers offered by the likes of Apple, Fitbit and Garmin.

“They’re convenient, small, portable and inexpensive, but you don’t use consumer items for life and death,” said Dr. Arthur Combs, chief medical officer at flexible electronics company MC10. Apple is reportedly developing glucose monitoring for the next generation of its Apple Watch.

Wearables are becoming more prominent in the regulated world of medical devices, pushing the envelope for monitoring different conditions.

MC10, for example, has created wearable patches for cardiac monitoring and ECG recording.

“The future of wearables has many different facets,” Combs said.

With his more than 20 years of medical device product development experience, suggests four ways that medical-grade wearables could transform healthcare in the future.
