The verb galvanize refers to stimulating muscles with an electrical current, and this word is also used to suggest stimulating someone into action. An inspiring speech can galvanize people into making a change.
The word galvanize was coined to honor the 18th-century scientist Luigi Galvani, who found that a spark could make a frog’s legs move. This discovery led to further studies in what Galvani called “animal electricity,” and became the basis for Mary Shelley’s Frankenstein, (a novel in which a mad scientist attempts to use electricity to galvanize a monster to life). Galvanize also means to cover steel or iron with zinc so it doesn’t rust.
stimulate (muscles) by administering a shock
