Bipolar electrodes are devices used in various applications, including medical and scientific fields, to measure electrical activity. They consist of two conductive elements that detect voltage differences between them. This setup allows for more accurate readings by minimizing interference from surrounding electrical noise. In medical settings, bipolar electrodes are often used in electrocardiograms (ECGs) to monitor heart activity. They can also be found in neurostimulation devices, where they help stimulate specific areas of the nervous system. Their design enhances signal quality, making them essential for precise diagnostics and treatments.
