What Are EEG Electrodes?
EEG electrodes are specialized conductive sensors placed on the scalp to detect and record the small electrical signals produced by brain activity. The electrodes transmit these signals through electrode leads to an EEG machine or electroencephalograph, where they are amplified, processed, and displayed as brainwave patterns.
The electrode-skin interface plays an important role in EEG recording quality. Proper electrode placement, good scalp contact, suitable conductive paste or gel, and appropriate impedance help achieve stable recordings and minimize unwanted electrical interference.
Types of EEG Electrodes
Different EEG applications require different electrode designs. Health Yantra Store offers a range of EEG electrodes suitable for routine EEG, long-term monitoring, sleep studies, and other neurodiagnostic applications.
Gold Cup EEG Electrodes are widely used reusable electrodes for routine clinical EEG. Their gold-plated surface provides good durability and corrosion resistance, making them suitable for repeated use when properly cleaned and maintained.
Silver/Silver-Chloride (Ag/AgCl) EEG Electrodes are commonly used for physiological and EEG signal recording. They are valued for their stable electrochemical characteristics and reliable electrode-skin contact.
Disposable EEG Electrodes are intended for single-use applications and are commonly selected where convenience and infection-control considerations are important. Adhesive and disc-style disposable electrodes are available for different monitoring requirements.
Adhesive EEG Electrodes feature an adhesive backing that helps secure the electrode to the scalp during routine EEG, ambulatory monitoring, and longer-duration recordings.
Pediatric and Neonatal EEG Electrodes are designed for applications involving infants and children, where appropriate electrode size and secure scalp contact are important.
Reference and Ground EEG Electrodes are used to establish the reference and ground connections required by an EEG recording system. Depending on the setup, these may include ear, mastoid, forehead, or other application-specific electrode designs.
What Is an EEG Electrode Cap?
An EEG electrode cap, also known as an EEG head cap, is a wearable cap designed to hold multiple EEG electrodes at predetermined positions across the scalp. Many EEG caps use standardized electrode placement systems such as the international 10–20 system, while high-density research caps may use 10–10 or other electrode configurations.
An EEG electrode cap helps simplify electrode placement and maintain consistent positioning between recordings. Depending on the design, EEG caps may be available in different channel configurations, including 19, 21, 24, 32, 64, and 128 channels.
EEG caps are commonly used for clinical EEG, epilepsy monitoring, neurological assessments, neuroscience research, sleep studies, and brain-computer interface (BCI) applications.
EEG Headband and EEG Helmet
An EEG headband or EEG helmet is a wearable device designed to hold EEG electrodes against selected areas of the scalp. Compared with a full EEG electrode cap, a headband or helmet may have fewer electrode positions and provide more targeted scalp coverage.
EEG headbands and helmets are commonly used in portable EEG, wearable EEG, research, BCI applications, and rapid brain activity monitoring. The appropriate design depends on the number of channels, electrode positions, recording requirements, and compatibility with the EEG system.
Wet vs Dry EEG Electrodes
Wet EEG electrodes use a conductive gel or paste between the electrode and scalp to establish electrical contact. Traditional gold cup and Ag/AgCl cup electrodes are commonly used with EEG conductive paste or gel and are widely used for clinical EEG recording.
Dry EEG electrodes are designed to operate without conventional conductive gel or paste. They use direct contact with the scalp or specialized conductive materials and are commonly used in portable, wearable, and research EEG systems where quick setup and reduced preparation are desirable.
The choice between wet and dry EEG electrodes depends on the recording application, electrode design, scalp conditions, required setup time, comfort, and EEG system specifications.
EEG Electrodes for Clinical EEG and Sleep Studies
EEG electrodes are an essential component of electroencephalography and can also form part of polysomnography (PSG) sleep study setups. During an EEG test, electrodes are positioned at specific scalp locations to record brain activity.
For routine EEG, electrodes are commonly positioned according to the 10–20 EEG electrode placement system. More advanced EEG applications may use higher-density electrode arrangements for increased spatial coverage.
In sleep laboratories, EEG electrodes may be used alongside other PSG sensors to monitor brain activity and help determine sleep stages and sleep-related physiological patterns.
How to Choose EEG Electrodes
When selecting EEG electrodes, consider the electrode material, reusable or disposable design, electrode size, connector type, lead length, number of electrodes required, and compatibility with your EEG machine.
For routine clinical applications, gold cup EEG electrodes and Ag/AgCl electrodes are commonly used. Disposable adhesive EEG electrodes may be preferred for single-patient or infection-control applications, while an EEG electrode cap or 10–20 EEG cap can simplify standardized multi-channel electrode placement.
Always verify the electrode connector and technical specifications with your EEG machine before purchasing replacement electrodes or caps.
EEG Electrode Price in India
The EEG electrode price in India depends on factors such as electrode type, material, brand, connector, reusable or disposable construction, and quantity. Basic EEG electrodes may start at approximately ₹200 per electrode, while branded, specialized, disposable electrodes and complete EEG electrode sets can cost more.
When comparing EEG electrode prices, consider the electrode material, durability, compatibility, intended application, and quantity rather than price alone.
How to Clean Reusable EEG Electrodes
Reusable EEG cup and disc electrodes should be cleaned after each use according to the manufacturer's instructions. First, remove the remaining conductive EEG paste or gel using soft gauze. Wash the electrode gently with lukewarm water and mild detergent, then rinse thoroughly with clean water.
For clinical use, disinfect the electrode using a method approved by the electrode manufacturer and your facility's infection-control protocol. Allow the electrode to dry completely before storage and inspect it for corrosion, damaged wires, loose connections, or remaining paste.
Avoid scraping the electrode with sharp or abrasive objects, and do not immerse electrical connectors or cable junctions unless specifically permitted by the manufacturer.
