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.

Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
