Capacitive refers to the ability of a material or device to store electrical energy in an electric field. This property is commonly found in capacitors, which are components used in electronic circuits to manage voltage and current. Capacitive sensors, for example, detect changes in capacitance caused by the presence of an object, such as a finger on a touchscreen.
In everyday technology, capacitive touchscreens are widely used in smartphones and tablets. They work by measuring the electrical charge from a user's finger, allowing for precise input without the need for physical pressure. This technology enhances user experience by enabling smooth and responsive interactions with devices.
