What is another term for an electrode?

An electrode is commonly referred to as a probe in many contexts, especially in fields involving electrical measurements or biochemical applications. In this context, a probe serves as a device that can detect or measure electrical signals, often used to explore or interact with a particular medium, such as skin tissue in aesthetic practices. This terminology emphasizes the role of the electrode as a tool that interfaces with the material being studied or treated.

Other terms listed, such as capacitor, transformer, and condenser, refer to different components used in electrical circuits and do not accurately describe the function of an electrode in the same way that "probe" does. A capacitor stores electrical energy, a transformer modifies voltage levels, and a condenser is often associated with capacitive components or systems that condense gases. None of these terms directly relate to the nature of an electrode as a measuring or testing instrument in the context presented.
