Galvanism refers to the contraction of a muscle that is stimulated by an electric current. The term was named after the scientist Luigi Galvani who investigated the effect of electricity on dissected animals in the 18th century.

History[edit]

Galvanism was discovered by Luigi Galvani in 1780 while he was working on frogs. He found that the muscles of dead frogs' legs twitched as if alive when struck by an electrical spark. This led to the development of the voltaic pile, the forerunner of the electric battery, by Alessandro Volta.

Galvanism in Literature[edit]

The concept of galvanism was utilized by Mary Shelley in her novel Frankenstein, where the protagonist, Victor Frankenstein, uses galvanism to give life to his creature.

Modern Usage[edit]

In modern times, galvanism refers to the induction of a direct current into the body through electrodes for therapeutic purposes. This is used in physical therapy and is known as galvanic stimulation or galvanic electrotherapy.
