Hi Geo

Found in the internet! In the web there are more! As they don't have ICs or transistors, skin was the voltage sensor!

Where on the internet? Before the telegraph, chains of people were sometimes used to communicate information. The people were connected together, and static electricity was used. It must have been pretty bad to be in that line of work.
