Capacitive

(Capacitive Touch)

Capacitive touch technology works by directly sensing the electrical properties of the human body.

Capacitive touch sensors can be embedded below specific points on a surface to create individual buttons, or over a large area, sensing the exact position of a finger on a display or other surface.

Capacitive touch sensors only respond to human flesh, so they generally do not work with a stylus or through a glove.

Unlike resistive technology, capacitive does not require pressure to activate; the lightest touch can trigger a capacitive sensor. In fact, actual contact is not always required. Some capacitive sensors are designed to work through one or more layers of other material and/or may be calibrated to respond even when a human finger is almost touching, but not quite.

Capacitive touch screens are generally considered more durable and reliable than resistive touch screens.
