Capacitive touch technology detects touch through the electrical properties of the human body. When a finger approaches a screen, it creates a change in the electric field, allowing the device to register the touch. This technology is commonly used in devices like smartphones and tablets, providing a responsive and intuitive user experience. Unlike resistive touch screens, which require pressure to register a touch, capacitive touch screens can detect lighter touches. This allows for multi-touch capabilities, enabling users to perform gestures like pinching or swiping. Capacitive touch is widely used in modern electronics, enhancing interaction with devices like smartphones and tablets.
