Our tool simulates the closed-loop interaction between a person with type 1 diabetes and an AID system: The body’s response to meals and administered insulin is simulated using a physiological model. The simulated glucose measurement is passed back to the AID algorithm – and the next cycle begins.

The results are visualized in interactive charts together with the algorithm output; this provides unprecedented possibilities to play around with the settings and gain insight into the closed-loop reaction.

Who can benefit from this project?

Below are some use cases where the simulator may be useful.

  1. Education: people with type 1 diabetes who already wear an insulin pump and are now considering switching to a closed-loop system, but want to understand in more detail how such a system works and how the outcome differs from manual therapy.
  2. Training: Staff in diabetes teams and clinics with the same goal as above.
  3. Research: Scientists who want to perform targeted in silico simulations, e.g. to evaluate strategies for the best possible treatment.
  4. Development: Developers or manufacturers of closed-loop systems who want to test new control algorithms or software versions. In particular, we want to attract new developers who have had little opportunity to contribute their own ideas in the past due to the lack of a test environment.

Curious?

Then just try the simulator, it works in every modern browser. In the methods section you will find technical details. The link to the software repository is provided in the open source section.
