Pressure sensors are devices designed to measure the force exerted per unit area, typically of gases or liquids. These sensors operate on diverse physical principles like piezoresistive, capacitive, or piezoelectric effects. Their functions are far – reaching. In industrial settings, they monitor fluid pressure in pipelines, ensuring optimal system operation and preventing over – pressure situations that could lead to equipment damage or safety hazards. In automotive applications, pressure sensors are used to measure tire pressure, which is essential for vehicle safety, fuel efficiency, and tire longevity. In medical devices, they can accurately measure blood pressure, providing crucial data for diagnosing and monitoring patients’ health conditions.
