Patent ID: 8272345

Claim:
An electrohydrodynamic spraying/spinning deposition system comprising: (a) a common source of pressurized fluent material within a manifold; (b) an array of 2 or more spraying/spinning tips, each one of the tips being fed from the common source of pressurized fluent material so as to provide a corresponding flow path for the fluent material; (c) a corresponding individual flow impedance device disposed within the corresponding flow path of each one of the tips between that tip and the pressurized fluent material source, each individual flow impedance device comprising a corresponding set of one or more orifices, wherein the sets of orifices for the tips of the array are formed in a common replaceable liquid-impermeable sheet; (d) a deposition surface; and (e) a high voltage source adapted and connected to create a high voltage potential applied between the tip array and the deposition surface.
