EarEEG is a novel recordings concept where electrodes are embedded on the surface of an earpiece customized to the individual anatomical shape of the users ear. A key parameter for recording EEG signals of good quality is a stable and low impedance electrode-body interface. This study characterizes the impedance for dry and wet EarEEG electrodes in a study of 10 subjects. A custom made and automated setup was used to characterize the impedance spectrum from 0.1 Hz - 2 kHz. The study of dry… 
Impedance and Noise of Passive and Active Dry EEG Electrodes: A Review
Dry electrodes are a promising solution for prolonged EEG signal acquisition, whereas wet electrodes may lose their signal quality in the same situation and require skin preparation for set-up. Here,
Earable Design Analysis for Sleep EEG Measurements
TLDR
This investigation presents a quantitative study of ear-electrodes with two electrode sizes at different locations in a wet and dry configuration and finds the location in the ear canal with the lowest impedance is ELE (Left Ear Superior), presumably due to increased contact pressure caused by the outer-ear anatomy.
Highly Porous Platinum Electrodes for Dry Ear-EEG Measurements
TLDR
These porous platinum electrodes could be used to measure the Berger effect in a dry state using just one ear of a test person, and their signal-to-noise ration and frequency transfer function is comparable to gel-based silver/silver chloride electrodes.
Highly Porous Platinum Electrodes for Dry Ear-EEG Measurements
TLDR
P porous platinum electrodes could be used to measure the Berger effect in a dry state using just one ear of a test person and their signal-to-noise ratio and the frequency transfer function is comparable to gel-based silver/silver chloride electrodes.
Dry-Contact Electrode Ear-EEG
TLDR
The study demonstrated that dry-contact electrode ear-EEG is a feasible technology for EEG recording, and represents an important technological advancement of the method in terms of user-friendliness, because it eliminates the need for gel in the electrode-skin interface.
A Two-Wired Ultra-High Input Impedance Active Electrode
TLDR
The proposed circuit reduces the input capacitance of a buffer amplifier while enabling measurements using leads with only two wires, providing a low-complexity and low-cost solution for interference rejection and artifact reduction in dc-coupled dry-contact biopotential measurements.
Soft pin-shaped dry electrode with bristles for EEG signal measurements
Abstract In this paper, we present a novel soft pin-shaped dry electrode for electroencephalography recording. The pins on dry electrode were fabricated from carbon fibers in order to achieve low
Reference configurations for ear-EEG steady-state responses
TLDR
This work presents a method for optimizing the reference configuration for steady-state type potentials, and demonstrates a robust SNR estimate, yielding on par or better SNR compared to other well-known methods.
A Novel Bristle-Shaped Semi-Dry Electrode With Low Contact Impedance and Ease of Use Features for EEG Signal Measurements
TLDR
A novel soft bristle-shaped semi-dry electrode for electroencephalography (EEG) recording that could work with drinking water instead of saline water and achieve even lower skin-electrode contact impedance than previous semi- dry or water electrode with saline water.
Physiological artifacts in scalp EEG and ear-EEG
TLDR
Ear-EEG was more prone to jaw related artifacts and less prone to eye-blinking artifacts compared to state-of-the-art scalp based systems, and spontaneous activity, in terms of alpha band oscillations, could be recorded from the ear- EEG platform.

TLDR
This analysis yields that noise bounds depend on features of the available devices as current and voltage noise, but the final noise level also depends on parasitic capacitances, requiring a careful shield and printed circuit design.
