7 results about "Contact electrification" patented technology

Contact electrification was an erroneous scientific theory from the Enlightenment that attempted to account for all the sources of electric charge known at the time. It has since been superseded by more modern notions. In the late 18th century, scientists developed sensitive instruments for detecting 'electrification', otherwise known as electrostatic charge imbalance. The phenomenon of electrification by contact, or contact tension, was quickly discovered.
