Violin plot of the wearing comfort ranking distribution for both electrode types and both body positions. Volunteers reported their perceived comfort at an overall number of 5 time points during the recordings: after initial cap application, at the end of the sitting recordings, at the beginning and end of the supine recordings, and at the overall end of the recordings (returned to sitting position). Indicated wearing times are grand averages calculated over all volunteers and both caps.

Dry electroencephalography (EEG) electrodes provide rapid, gel-free, and easy EEG preparation, but with limited wearing comfort. We propose a novel dry electrode comprising multiple tilted pins in a flower-like arrangement. The novel Flower electrode increases wearing comfort and contact area while maintaining ease of use. In a study with 20 volunteers, we compare the performance of the novel 64-channel dry Flower electrode cap to a commercial 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. Channel reliability and signal quality were shown to be equivalent for the novel Flower and conventional Multipin dry electrodes.
