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.

Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
