Engineers developed improved electrode technology for electroencephalography systems that record electrical activity from the scalp during clinical diagnosis and research, delivering more reliable brain activity readings than conventional designs.
Electroencephalography, or EEG, is used to evaluate conditions such as epilepsy, sleep disorders, and certain brain injuries. Signal quality depends heavily on stable contact between electrodes and the skin; poor contact introduces noise that can obscure clinically meaningful patterns.
The upgraded electrodes aim to reduce artifacts caused by patient movement and fluctuating skin impedance, problems that often force repeat testing or complementary invasive monitoring in hospital neurology departments.
Developers said the technology was evaluated under conditions intended to mirror routine clinical use. More dependable recordings could help clinicians make diagnostic and treatment decisions with greater confidence during extended monitoring sessions.
