TLDR
In this paper, the potential and impedance variations were measured for electrode movements in electrolytes, and the streaming potentials were electrolyte-concentration dependent and in the order of 10μV.Abstract:
Movement-induced potentials of streaming potential type were studied in various electrode configurations. The geometric design of the electrode was important for the reduction of noise generated by the movements of gel. Potential and impedance variations were measured for electrode movements in electrolytes. The impedance variations were small and the streaming potentials were electrolyte-concentration dependent and in the order of 10μV. The same type of study was carried out for electrodes applied to the skin. The conclusion from this experiment is that skin deformation potentials dominate the disturbance pattern in this type of recordings.read more

Optimal EMG signal bandwidth and interelectrode distance for the recording of acoustic, electrocutaneous, and photic blink reflexes.
TL;DR: The bandwidth for the recording of the orbicularis oculi blink reflex electromyogram response is optimal when low-frequency artifacts, such as motion artifacts and cross-talk from other muscles, are maximally suppressed, whereas true EMG signal power is maximally retained.

The origin of skin-stretch-caused motion artifacts under electrodes
TL;DR: The model of Thakor and Webster is expanded to best fit the waveform of delta V and delta Z caused by stretch, which has a rectangular shape waveform, whereas the rising edge of delta Z shows a fast followed by a slow component and its falling edge decays exponentially with a large time constant.

Physicochemical Properties of Cartilage in the Light of Ion Exchange Theory
TL;DR: The concentration of fixed negatively-charged groups in cartilage was shown to be the most important parameter and fixed charge density was found to increase with distance from the articular surface and this variation was reflected in the other properties.
