How to obtain ESPARGOS?

We have started to provide ESPARGOS devices to research groups and industry partners within the EU, but availability ist still extremely limited. We are currently working on scaling up production in summer 2026, but many legal and some technical challenges are still being sorted out. If you would like to be notified when ESPARGOS becomes more widely available, please sign up for updates below. In the meantime, check out our public datasets!
