An electrohydrodynamic spraying or spinning deposition system, which
includes a common source of pressurized liquid within a manifold, and an
array of 2 or more spraying tips, each tip being fed from the common
source of pressurized liquid to create a liquid flow path. An individual
flow impedance device is disposed within each tip's individual liquid
flow path from the pressurized 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 between the tip array and a
deposition surface.
