DIGITAL ELECTROSPINNING ARRAY

A method includes applying pressure to a liquid feed of nanofiber material at a first nozzle of an array of nozzles having a first electrode voltage applied to a first electrode within an array of nozzles to form a first enlarged meniscus having a nanofiber attached, applying pressure to the liquid...

More Information
Summary:A method includes applying pressure to a liquid feed of nanofiber material at a first nozzle of an array of nozzles having a first electrode voltage applied to a first electrode within an array of nozzles to form a first enlarged meniscus having a nanofiber attached, applying pressure to the liquid feed at a second nozzle having a second electrode voltage applied to a second electrode and adjacent the first nozzle within the array to form a second enlarged meniscus, increasing the second electrode voltage applied to the second electrode to a voltage level equal to voltage applied to the first electrode when the first and second enlarged menisci meet and form a combined meniscus with the nanofiber attached, decreasing the first electrode voltage to zero, and decreasing pressure on the liquid feed at the first nozzle to separate the first enlarged meniscus at the first nozzle from the second enlarged meniscus at the second nozzle having the nanofiber attached.
