World's first 3-D-printed 'Sneezometer' will help asthma patients breathe easy

(University of Surrey) Research from the University of Surrey has led to the development of the world's first 'sneezometer,' an airflow sensor or 'spirometer' that is sensitive enough to measure the speed of a sneeze. For use in diagnosing a variety of respiratory conditions, the sneezometer is twice as fast, and more sensitive than any other available device.
