What can electrodes be made of?

Explanation:
Electrodes only need to be conductive and safe for skin contact, and in practice they come in several common forms. You’ll find metal electrodes, conductive rubber or carbon-loaded rubber electrodes, and disposable adhesive electrodes with conductive gel. That mix—rubber, metal, or disposable—captures the main types you’ll encounter in electrotherapy, from reusable metal or carbon rubber pads to single-use, pre-gelled pads. Plastic by itself isn’t typically conductive for skin contact, and glass or ceramic aren’t standard choices for routine therapeutic electrodes because they’re not practical for everyday skin application.
