Ag/AgCl-Coated Silver Tube Dry EEG Electrode
The Ag/AgCl-Coated Silver Tube Dry EEG Electrode is a compact tubular contact component developed for EEG biosignal acquisition and custom electrode assemblies. The reference design uses a silver-based metal tube with a silver/silver chloride surface treatment.
Unlike multi-prong or flat disc electrodes, this design features a slim, hollow tube structure. Its dimensions, exposed contact area and connection method can be specified for compatible EEG sensors, research equipment and custom electrode holders.
Hollow Tube Structure for Compact EEG Sensor Designs
The tubular shape provides an alternative to conventional disc and comb-style EEG electrodes. Its small cylindrical profile can be considered for sensor assemblies where mounting space, contact geometry and electrical termination need to be designed together.
The reference product lists a 10mm specification. Actual tube length, outer diameter, inner diameter and tolerances must be confirmed from the approved drawing before production.
Silver Material with Ag/AgCl Surface Treatment
The reference electrode uses silver material with an Ag/AgCl surface treatment for bioelectrical signal applications. The material and surface-finish specifications should be selected according to the intended EEG contact conditions.
This surface-treated construction differs from the powder-sintered structure of our Columnar Sintered Ag/AgCl Electrode. The two electrode types require separate evaluation of material, contact geometry and application conditions.
Integration into EEG Electrode Holders
The silver tube is an electrode contact component rather than a complete ready-to-wear EEG sensor. It can be evaluated for installation in a compatible insulating holder, with the exposed contact area and lead-wire connection defined by the equipment design.
The mounting arrangement should support the electrode mechanically while maintaining the required electrical connection. Contact pressure, insulation, wire attachment and the intended scalp-contact method must be confirmed during sensor development.
Other scalp-contact designs and matching lead wires are available through our EEG & EMG Electrodes & Cables product range.
