We are the OPEN project, a European Union-funded international research consortium aiming to study and explore the unique patient innovation of “Do-It-Yourself Artificial Pancreas Systems”, or DIYAPS. We are asking people with diabetes who are or whose child is using an open-source closed-loop system or who are interested in this technology to help us build evidence on how this technology affects the lives of people with diabetes.

The survey is open again

We have reopened the survey for new participants, significantly reducing the number of questionnaires. We now want to focus more on your thoughts about or experiences with DIYAPS.

You can donate your device data, too!

Regardless of if you have participated in our survey last year, or if this is your first time, you still have the option to anonymously donate your device data (e.g. from Nightscout) if you have previously registered for a Participant ID. This would GREATLY HELP our aim of exploring improvements to the (DIY)APS experience for all, now and in the future.

Further information will be provided on the next pages and here on our website.

Do you already have a Participant ID?
I do not have a Participant ID.I already have a Participant ID.

Last but not least: We are very happy to have all of you here! THANK YOU!
