Pressure-sensitive refers to materials or devices that respond to applied pressure. These materials can change their properties or behavior when force is exerted on them. Common examples include pressure-sensitive adhesives, which bond surfaces together when pressed, and pressure-sensitive labels, which stick to surfaces without needing heat or water. In electronics, pressure-sensitive technology is used in devices like touchscreens and sensors. These devices detect touch or pressure and translate it into actions, such as opening an app or adjusting settings. This technology is widely used in smartphones, tablets, and various industrial applications.
