Capacitive sensing

Capacitive sensing is a technology that detects touch and proximity by measuring changes in electrical capacitance. It works by using conductive materials, such as your finger, which alters the electric field around a sensor. When you touch the sensor, it senses the change in capacitance, allowing devices to interpret your input. This technology is commonly found in smartphones, touchscreens, and even home appliances, enabling them to respond to human interaction without requiring physical buttons. Its advantage lies in durability and ease of use, as it can work through surfaces like glass or plastic.
