Abstract: The physics of colloidal suspensions of anisotropic particles has been a topic of research since almost a decade now. Such suspensions show a variety of unique properties depending on the paticle concentration and on external fields.

Here, we report the relaxation of electric -field-induced inhomogeneities in particle concentration. The occurring patterns can be static or dynamic. For our experiments, we use electro-responsive suspensions of pigment particles "Novoperm Carmine HF3C" (Clariant) with an aspect ratio of abourt 1:5 in a nonpolar solvent.
