Using a tiny piezoelectric "pill," the Tecno electronic-pneumatic regulator almost instantly limits airflow. When a low power drive signal is applied, the device's piezoelectric element changes shape and regulates pneumatic pressure through an airway. Because it has no moving parts, Tecno is reportedly wear-free. It is not affected by magnetic fields and generates no heat or sparks, making it suitable for use in hazardous operating environments. Applications for the piezo-based pressure regulator include ultrasound welding equipment, sheet tension winding machinery, and highly sensitive medical equipment, such as breathing apparatus or blood pressure monitoring systems.
