Analytical and computational results concerned with modelling of the piezo-particulate composite structure formation during dielectrophoresis are analysed. A numerical model has been put forward to simulate the ceramic-particleferroelectric ceramic alignment and structure formation in a viscous medium during dielectrophoresis, and the system ‘ferroelectric ceramic particles + medium’ is assumed to be semi-dilute. The main parameters to be considered during this modelling are the order parameter and total chain perfection degree. These parameters are inseparably linked with some microgeometric characteristics of the system of the ceramic particles in the continuous viscous medium. The performance of the aforementioned model is demonstrated for a variety of systems based on ferroelectric ceramic particles in a viscous polymer medium.
