The best way to monitor EEG

SOENIA® UltimateEEG™ Electrode, a subdermal, implantable and flexible electrode, is currently entering clinical trials in Tampere University Hospital, Tampere, Finland.

Surface recording versions of the UltimateEEG™ Electrode are CE-marked and readily available for use.


The SOENIA® UltimateEEG™ Electrode is novel, flexible and customizable electrode. We are currently testing our subdermal electrode in clinical trials, but we are already offering it for R&D purposes for surface measurements. Contact us for more detailed information.

Tested technology

We have been comparing our electrode to hospital gold standard surface electrodes, and the SOENIA® UltimateEEG™ Electrode has performed equally well while fitting 8 channels to the surface area of one standard Ag-AgCl electrode.

Fast customization

We can offer you customized electrodes for your R&D purposes in a fast turn over rate. Contact us, and we will discuss what would best suit your needs.

Novel technology

We developed our electrode technology in Tampere University of Technology, Finland. The SOENIA® UltimateEEG™ Electrode is patent pending (granted already for example in Australia).
