When I first saw this article, I was intrigued. Living with type 1 diabetes means pricking my finger five or more times a day, so the idea of a glucose sensor that lasts a full year — and works with an automated insulin pump — felt huge. And now it’s real.
The twiist AID system, created by Sequel Med Tech and Senseonics, is the first FDA-cleared automated insulin delivery (AID) system using a 1-year sensor: the Eversense 365.
It combines:
- A small sensor implanted in the upper arm
- A rechargeable skin-worn transmitter
- The reusable twiist insulin pump (up to 3 years, with a 300-unit reservoir)
- The twiist Loop algorithm (based on Tidepool Loop) for automatic insulin adjustment
Benefits:
- Fewer sensor changes
- Precise microdosing with direct volume measurement
- Less daily hassle with stronger long-term control
The sensor still requires a weekly calibration, but this could be a big step toward simpler diabetes management. As implantable devices become more common in chronic care, expect to see more long-wear systems that combine monitoring and treatment in one.
This tech could change daily life for people with diabetes — and I can’t wait to see it in action.
