Towards Reliable and User-Friendly Water-Based EEG Home Monitoring
A Signal-Quality Driven Guidance Interface
Master thesis
(2025)

C.E. Luijendijk, Arthur R. van Nieuw Amerongen, Roland D. Thijs, M.L. van de Ruit, Else A. Tolner
- This thesis presents a control metric designed to create clinically interpretable, high–signal quality recordings with water-based EEG, utilizing impedance and zero-crossings
- The metric was integrated into a newly developed, intuitive, user-centred interface for independent patient use in a home environment.
- A home study using this interface demonstrated that it enabled independent use. Approximately half of the recordings were clinically interpretable, the other half were not, primarily due to low-voltage signals. Signal quality was lower than in previous studies conducted under technical supervision.
- The metric requires further optimization to improve signal quality and clinical interpretability, with strict electrode-specific impedance (<100 kΩ) and low-voltage signal handling.
- In a controlled environment, prolonged water-based EEG recordings of up to three hours were feasible, with stable signal quality and acceptable user comfort.
- The usability of the proposed solution should be further validated in people with epilepsy. Its potential role between wearable solutions and inpatient monitoring for therapeutic applications should be further established.
