His early model consisted of two sheets of coiled lead soaked in sulfuric acid, but he soon revised this design, and just a year later, he presented a nine-cell version to the Academy of Sciences. What mechanical device did PlantÃ© invent as part of his investigation into the differences between static and dynamic electricity?
