Electroencephalograms (EEG) are essential tools for monitoring brain activity, widely used in neurological research and clinical diagnostics. Traditional wet electrodes, while effective, pose limitations for long-term EEG monitoring due to the need for conductive gels, which dry out over time and degrade signal quality. To address these issues, we developed an active dry electrode designed specifically for EEG acquisition, which includes integrated amplification and filtering stages utilizing compliance capacitance. Our design consists of a custom-made capacitive electrode and a high-impedance preamplifier, built on a dual-PCB setup that minimizes noise and interference. Laboratory tests demonstrated the electrode’s ability to maintain signal fidelity across a range of frequencies relevant to EEG, highlighting its potential as a robust alternative for prolonged monitoring without the drawbacks of conventional wet electrodes.
