SPREE AIF Project Soft Polymer Dry Electrodes for EEG Acquisition


 

Overview

Electroencephalography is the gold standard for non-invasive brainwave measurements in research, diagnostics and therapy. Due to the simplification of application, material and time savings as well as the reduction of environmental pollution, dry electrode technologies are gaining importance and enable new applications in the field of medicine and mobile EEG acquisition. Conductively coated polymer substrates have proven to be the most successful technology for dry electrodes. The multi-step coating process currently requires hard polymer substrates, which results in limitations in electrode reliability, signal quality and wearing comfort. The aim of the project is to explore a new coating technology that can reliably coat soft, arbitrarily shaped polymer substrates in quantities relevant for multi-channel hood systems. The targeted production efficiency will contribute to a reduction in the cost of dry EEG systems. The more flexible dry electrodes make it possible to significantly increase wearing comfort, reliability and long-term applicability, thus enabling clinical and home applications.
