====Historical Context of Electricity==== | |||
Organisms can be characterized by their ability to conduct electricity, which has been known since the second half of the 18th century. Edmund Whittaker (1910) mentioned Luigi Galvani's and his assistants' experiments in the 1780s, which demonstrated convulsions in frog legs when attached to an electrical machine, and which were considered “animal electricity.” A slightly different approach to electricity was presented by Alessandro Volta, who, in 1799, built his Voltaic Pile, known as the first electrical battery (RSC 2015). Described as a reaction between chemical elements, the Voltaic Pile had two electrodes of different metals placed between pads made of moist material. Such a setup made it possible to demonstrate interaction between organic and non-organic matter. | |||
The characterization of organisms capable of electrical conductivity in reference to reactions between nerves (organic) and metals (non-organic) instead of “animal electricity” was introduced by Johann Wilhelm Ritter (Berg 2008) after a number of experiments shortly before his death in 1810. | |||
