capacitive
Stores electrical charge
Capacitive describes something that works by sensing electrical capacitance—the ability to store an electric charge.
A capacitive touchscreen responds to the slight electrical conductivity of a fingertip rather than physical pressure: The capacitive display won't register input from a stylus unless it's specially designed.
Capacitive sensors detect presence or proximity without mechanical contact.
