A bipolar electrode is a type of electrical device used in various applications, including electrochemistry and medical devices. It consists of two conductive materials that allow for the flow of electric current. Unlike a traditional electrode, which has a single point of contact, a bipolar electrode can facilitate reactions at both ends, making it efficient for certain processes. In medical applications, bipolar electrodes are often used in procedures like electrocardiograms (ECGs) and electroencephalograms (EEGs) to measure electrical activity in the heart and brain. Their design helps improve signal quality and reduce noise, providing clearer data for diagnosis and monitoring.
