Compatibility
These electrodes are compatible with any biopotential amplifier that accepts a snap connector, such as the AD8232 ECG module, Muscle Sensor v3, and standard EEG headboxes. They can be used with development boards like Arduino and Raspberry Pi via suitable analog front-end modules.
Wiring Notes
Connect the snap lead wire to the electrode's stud, then to your amplifier's input. Ensure the skin is clean and dry for best adhesion. For ECG, place three electrodes: right arm, left arm, and right leg drive. For EMG, place along the muscle belly and reference on bony area.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with standard ECG amplifiers?
Yes, these electrode patches use a 4 mm snap stud compatible with most ECG lead wires and bioamplifier modules like the AD8232.
Can these electrodes be reused?
These are single-use electrodes. Once opened, the gel dries out and adhesion weakens. For consistent signal quality, replace after each use.
What is the shelf life of these electrode patches?
They have a shelf life of 2 years from the date of manufacture when stored in a cool, dry place. Each patch is individually sealed to maximize freshness.
