Abstract
The possibility to use periodically poled lithium niobate structures for dielectrophoretic trapping of dielectric particles was investigated. The trapping effect was achieved through the development of opposite electrical charges on z+ and z- faces of a crystal when subject to temperature variation. Appropriate oil suspensions of dielectric particles were used for the experiments which show the possibility to trap those particles by means of the pyroelectric effect in correspondence of the reversed ferroelectric domain areas. Results are presented while perspectives of exploitation in different fields are illustrated.
