ELECTROSPRAYING/ELECTROSPINNING ARRAY UTILIZING A REPLACEABLE ARRAY OF INDIVIDUAL TIP FLOW RESTRICTORS

摘要

An electrohydrodynamic spraying or spinning deposition system, which incl udes a common source of pressurized liquid within a manifold, and an array o f 2 or more spraying tips, each tip being fed from the common source of pres surized liquid to create a liquid flow path. An individual flow impedance de vice is disposed within each tip's individual liquid flow path from the pres surized liquid source into each spraying tip. The individual flow impedance devices are disposed within a replaceable sheet, which can be easily cleaned or changed to accommodate the instance liquid viscosity and composition. A high voltage source is applied to create a high voltage potential applied be tween the tip array and a deposition surface.
