The term "galvanization" is derived from the name of the Italian scientist Luigi Galvani. Today, the phrase "galvanize" usually refers to the process of covering base metals with zinc, but it was originally used to indicate "providing electric shocks." Luigi Galvani researched "bioelectricity," He was interested in the human nervous system and how to generate and respond to electrical patterns. When he shocked a dead frog's limb with an electrical spark, the muscles twitched, and he realized that bodies generate electricity.
