WebSep 9, 2024 · Galvani’s great breakthrough had come on 20 September 1786, when he had discovered – quite by accident – that the spinal cords of a frog carried an electric charge. Galvani believed he had found proof of what he called ‘animal electricity’, an innate force in the body’s nerves. WebThe frog galvanoscope was a sensitive electrical instrument used to detect voltage in the late eighteenth and nineteenth centuries. It consists of skinned frog's leg with electrical connections to a nerve. The instrument was invented by Luigi Galvani and improved by Carlo Matteucci.
