概要
- 論文の詳細を見る
Experimental and theoretical studies on the applied voltage-displacement characteristics of a piezoelectric series type bimorph were performed. The displacement increased with an increase in the applied voltage until dielectric breakdown. An electric field higher that its coercive field (E_c) can be applied to the bimorph, because its poling direction is opposite to the field, owing to an electric charge balance between its two layers. On the other hand, the displacement of a parallel-type bimorph fell to zero when the applide voltage per unit length equalled E_c. The series-type bimorph displayed larger displacement and higher reliability than the parallel-type bimorph.
