Disposable electrodes are one-time-use components used in various medical and diagnostic procedures to detect and record electrical activity from the body. These electrodes are essential parts of tests like electrocardiograms (ECG), electroencephalograms (EEG), and electromyograms (EMG). 

The disposable electrodes detect the electrical signals from the body, such as heart rhythms, brain activity, and muscle contractions. The disposable electrodes are an integral part of modern diagnostic procedures offering better balances of conveniences, accuracy, and hygiene. 

These are essential tools for various medical settings and ensuring reliable monitoring.

The primary function is to capture electrical signals generated by the body. These electrodes act as conductors, transmitting the electrical activity with minimal interference to the monitoring equipment. There are various disposable electrode types like ECG electrodes (different shapes and sizes), EEG electrodes (configurations based on EEG type), and EMG electrodes (surface or needle types).

Disposable electrodes can be used in EP studies to assess the functionality of the nervous system by recording electrical responses to specific stimuli (visual, auditory, etc.).
