Testing the need for carbon in salt/adhesive electrodes for surface electromyography measurements: Preliminary results.

We compared previously carbon/salt/adhesive (CSA) electrodes with Ag/AgCl electrodes for surface electromyography (sEMG) signals collection. We found no differences in amplitude, but CSA electrodes exhibited a significantly better response to noise and motion artifacts. However, the carbon component may not be needed, and the salt/adhesive (SA) mixture might be as good as CSA for such a task.

Novel dry electrodes for recording electrodermal activity.

Novel carbon/salt adhesive (CSA) electrodes have been found suitable for collecting electrodermal activity (EDA) signals. Ag/AgCl electrodes are considered the standard for collecting EDA signals, because it highly avoids electrodes' polarization. Ag is an expensive commodity.

Assessment of Carbon/Salt/Adhesive Electrodes for Surface Electromyography Measurements.

This paper presents the evaluation of novel electrodes for surface electromyography (sEMG) measurements. The electrodes are based on the mixture of carbon powder, quaternary salt, and viscoelastic polymeric adhesive (carbon/salt/adhesive or simply CSA), which when combined, provide the unique advantages of having longer (theoretically infinite) shelf life and potentially lower cost than Ag/AgCl hydrogel electrodes, consistent with FLEXcon's Patent #8 673 184. The 20 subjects were recruited to collect simultaneous recordings of sEMG signals using Ag/AgCl and CSA electrodes, side-by-side on triceps brachii, tibial anterior muscles, biceps brachii, and quadriceps femoris.

Low Impedance Carbon Adhesive Electrodes with Long Shelf Life.

A novel electrocardiogram (ECG) electrode film is developed by mixing carbon black powder and a quaternary salt with a visco-elastic polymeric adhesive. Unlike traditional wet gel-based electrodes, carbon/salt/adhesive (CSA) electrodes should theoretically have an infinite shelf life as they do not dehydrate even after a prolonged period of storage. The CSA electrodes are electrically activated for use through the process of electrophoresis.

Developing pressure sensitive adhesive electrodes: preliminary results.

A mixture of carbon black powder, polar organo salt and a pressure sensitive adhesive (PSA) has shown to be able to collect skin bio potentials. Such PSA electrodes do not dehydrate even after a prolonged period of storage, which leads to a theoretically infinite shelf life. The PSA electrodes need to be electrically activated through electrophoresis.
