Jens Haueisen received an M.S. and a Ph.D. in electrical engineering from the Technische Universität Ilmenau, Germany, in 1992 and 1996, respectively. From 1996 to 1998 he worked as a Post-Doc and from 1998 to 2005 as the head of the Biomagnetic Center, FriedrichSchiller-University, Jena, Germany. In 2003 he received the habilitation (professorial thesis). Since 2005 he is a Full Professor of Biomedical Engineering and directs the Institute of Biomedical Engineering and Informatics at the Technische Universität Ilmenau, Germany. His research interests include the investigation of active and passive bioelectric and biomagnetic phenomena.
We propose a novel dry electrode comprising multiple tilted pins in a flower-like arrangement. In a study with 20 volunteers, we compare the performance of a novel 64-channel dry Flower electrode cap to a dry Multipin electrode cap in sitting and supine positions.
The wearing comfort of the Flower cap was rated as significantly improved both in sitting and supine positions. The channel reliability and average impedances of both electrode systems were comparable. Averaged VEP components showed no considerable differences in global field power amplitude and latency, as well as in signal-to-noise ratio and topography. No considerable differences were found in the power spectral density of the resting state EEGs between 1-40 Hz. Overall, our findings provide evidence for equivalent channel reliability and signal characteristics of the compared cap systems in the sitting and supine positions.
The novel Flower electrode increases wearing comfort and contact area while maintaining ease of use as a dry EEG electrode.
The reliability, signal quality, and significantly improved wearing comfort of the Flower electrode allow new fields of applications for dry EEG in long-term monitoring, sensitive populations, and recording in supine position.
