Capacitive touch panel manufacturers tell you that capacitive touch technology relies on the capacitance of the human body, not pressure like resistive technology. There are two types of capacitive touch panels, surface capacitive technology and projected capacitive technology, both of which work by detecting changes in capacitance on the screen.

Surface capacitive touch panel: used for larger size touch screen products that require less precision. The touch screen is covered with a thin glass surface. Under this glass surface, there is a protective layer covered with a thin layer of electrodes. The electrodes on the corners of the panel supply voltage to the thin film layer. When the finger touches the screen, a small charge is transferred to the finger and the circuit is complete, which creates a voltage drop at that spot on the screen and the touch is detected. That's why you can't use a capacitive touchscreen while wearing gloves.
Projected capacitive touch panel: More sophisticated capacitive touch technology for smaller size touch screen products as it is more accurate than surface capacitive touch panel. Under the glass with the protective cover, there is a pattern or matrix of electrode layers. This pattern forms the plane of X and Y coordinates that the controller uses to count touch events.
Capacitive touch panel is a better choice if you need to use for higher precision application system. With the capacitive touch panel, multi-touch is not a problem, you can scroll easily and have excellent operating sensitivity.
