Q. What is Capacitor-Based Keyboards?
These keyboards are based on the idea of Capacitance. A simple capacitor comprises a pair of conductive plates having opposite charges and separated by an insulator. This arrangement produces a field between plates proportional to closeness of plates. Changing the distance between plates roots current to flow. Capacitive keyboards have etched circuit boards with tin and nickel-plated copper pads performing as capacitors under every key (a key is technically known as a station). Every key press presses a small metal-plastic circle down causing electric flow. These keyboards work well however have the drawback that they follow an indirect scheme though they have a longer life than contact-based keyboards. These keyboards were initiated by IBM.
