Dielectrophoretic adhesion of 50-300 µm particles under ambient atmospheric conditions
Dielectrophoretic adhesion of 50-300 µm particles under ambient atmospheric conditions
The SPABRINK EU project required temporary adhesion of coloured solid “ink” particles to form an image. We use dielectrophoretic force to attach ink particles under the field from a voltage applied to an interdigitated electrode on the image carrying surface.
Finite element modeling results were compared in terms of an “adhesion factor” that included the density of particles as well as dielectric constant. In our experiments 50e300 mm alumina, silica sand and polymer particles were shown to adhere to a vertical plane electrode structure under laboratory ambient atmosphere.

Abstract
The SPABRINK EU project required temporary adhesion of coloured solid “ink” particles to form an image. We use dielectrophoretic force to attach ink particles under the field from a voltage applied to an interdigitated electrode on the image carrying surface.
Finite element modeling results were compared in terms of an “adhesion factor” that included the density of particles as well as dielectric constant. In our experiments 50e300 mm alumina, silica sand and polymer particles were shown to adhere to a vertical plane electrode structure under laboratory ambient atmosphere.
