Human eye inspires clog-free ink jet printer

July 16, 2012 10:10 am | News | Comments

University of Missouri engineers have recently invented a clog-preventing nozzle cover by mimicking the human eye. The invention uses a droplet of silicone oil to cover the opening of the nozzle when not in use, similar to the film of oil that keeps a thin layer of tears from evaporating off the eye. Instead of eyelids, however, researchers came up with a different solution.
