Relating to the generation of electric charge through friction between different materials.
The triboelectric effect can be observed when you rub a balloon on your hair.
Triboelectric → It is formed from "tribo-" (from Greek "tribein", meaning to rub) and "electric" (from Greek "ēlektron", meaning amber, which is associated with electricity). The word describes electricity generated by rubbing materials together.
Think of 'rubbing' ('tribo-') materials to create 'electricity' ('electric') — that's how triboelectricity is generated.
