Luigi Galvani's discovery, often called “animal electricity”, refers to his observation that a frog's muscles twitched when they came into contact with two different metals. Galvani believed these muscle twitches were caused by an electrical fluid in the body. Although he did not fully understand the exact nature of this "animal electricity", his discovery laid the foundation for the understanding of bioelectricity. It inspired Alessandro Volta to invent the first battery.
