Capacitive keyboard

What is capacitive keyboard?
A capacitive keyboard is a type of computer keyboard that uses a change in capacitance on the capacitor pad to detect a pressed key on a keyboard. It offers features similar to a standard contact keyboard, but its internal structure is different and is faster and more reliable.

Capacitive keyboards mainly work by sensing the change in capacitance on a capacitor pad that is spread across the entire keyboard. In contrast to conventional keyboards, where the current flow is triggered internally by pressing a key, current always flows into the capacitive keyboard. Static charges are stored in capacitors under each key. When a key is pressed, it connects to the capacitor pads and changes the capacitance at that specific point on the capacitor pad, which the keyboard identifies and registers as the exact key press. Capacitive keyboards are faster than contact keyboards because they only require a light keystroke to register a keystroke.
