1971年意大利波仑亚大学解剖学家伽伐尼发表了一篇论文《论肌肉运动中的电力》。1973年,伽伐尼来到英国皇家学会,表演他的这个发现。他在台上布置好实验桌,打横放一根细铁梁,上面挂上一溜铜钩,将青蛙解剖后一个一个地挂在铜钩上,不想蛙腿竟轻轻动弹起来,这使在座的众位教授、学者们目瞪口呆。实验完毕,伽伐尼还讲述了动物身上带电的理论。 In 1971, Galvani, an anatomist at the University of Bologna, Italy, published a paper entitled “Electricity in Muscle Movement.” In 1973, Galvani came to the Royal Society to perform his discovery. He arranged a good experimental table on the stage, playing a thin iron beam transversely, hanging a slippery copper hook, hanging the frogs one by one on the copper hooks, and did not want the frog legs to move softly, All professors, scholars stunned. At the end of the experiment, Galvani also talked about the theory of electrification in animals.
