Capacitive touchscreens

Capacitive touchscreens detect touch by measuring changes in electrical charge. When you touch the screen with your finger, which conducts a small amount of electricity, it alters the electrostatic field on the surface. These changes are detected by sensors, allowing the device to pinpoint your finger's location accurately. This technology is commonly used in smartphones and tablets because it responds quickly and supports multi-touch gestures. Unlike resistive screens that rely on pressure, capacitive screens need only a light touch, providing a smooth, responsive experience suitable for modern interactive devices.
