A col­lab­o­ra­tion for smarter, more sus­tain­able neu­rotech­nol­o­gy

Screen­tec and Plux Biosig­nals have achieved a major mile­stone in the EU and Busi­ness Finland–funded Sus­tron­ics project by devel­op­ing and test­ing next-gen­er­a­tion print­ed EEG elec­trodes that com­bine high per­for­mance with more sus­tain­able mate­ri­als.

Sus­tron­ics Pilot 2.1 test­ed sev­er­al sin­gle-lead EEG elec­trode vari­ants from Screen­tec, com­bin­ing dif­fer­ent sub­strates and con­duc­tive mate­ri­als such as paper, cop­per, and car­bon. Per­for­mance was bench­marked against Car­di­nal­Health™ Kendall™ hydro­gel elec­trodes, the cur­rent clin­i­cal gold stan­dard, using biosig­nal­splux EEG sen­sors under con­trolled lab con­di­tions.

Key find­ings

The results show that Screentec’s elec­trodes deliv­ered EEG per­for­mance near­ly iden­ti­cal to the ref­er­ence elec­trodes across all fre­quen­cy ranges. The paper-based vari­ant stood out, achiev­ing the low­est error rates, sta­ble fre­quen­cy response, and min­i­mal 50 Hz inter­fer­ence, with less than 3% devi­a­tion in key EEG bands com­pared to con­ven­tion­al sen­sors.

Devel­oped with recy­clable and bio-based mate­ri­als, the best-per­form­ing vari­ant used paper as the sub­strate and cop­per-based con­duc­tive traces, mak­ing it sig­nif­i­cant­ly more envi­ron­men­tal­ly friend­ly than tra­di­tion­al PET + sil­ver designs. The elec­trodes were com­fort­able to wear, easy to remove, and left no residue on the skin.

By com­bin­ing Screentec’s print­ed elec­tron­ics exper­tise with Plux’s biopo­ten­tial sig­nal ana­lyt­ics, the project is a great exam­ple of how Euro­pean col­lab­o­ra­tion can turn great ideas into prac­ti­cal and more sus­tain­able health­care solu­tions.
