Field controlled direct-write electrospinning

Abstract

The invention provides a method for producing fibers, the method having the steps of producing electrospun fiber; and directing the fiber to a plurality of targets, whereby only one of the targets is grounded at any one time. Also provided is a system for producing anisotropic fibers having a reservoir of electrospun fiber constituent' wherein an egress point of the reservoir is electrically charged; a plurality of electrodes opposed to the egress point, wherein only one of the electrodes is grounded at any one time while the remaining electrodes are at an initial floating voltage state; and a target substrate disposed between the egress point and the plurality of electrodes.
