Popis: A dome piezoelectric-electrostrictive monolithic bilayer composite (PE-MBLC) actuator is attached to a thin metallic plate by insulating epoxy resin to form a flextensional actuator. Such flextensional actuator is called bilayer piezoelectric/electrostrictive dome unimorph (BIPEDU). Under the application of an electric field, the force generated from radial contraction of PE-MBLC was transferred through the bonding area to deform the metallic plate, generating more displacement in BIPEDU actuator. In this study, a PE-MBLC with the P:E volume ratio of 8:2 was used as the active driving element and a metallic plate served as a flextensional structure. Different type of metallic plates showed different in the flexibility which will effect to strain amplification in BIPEDU. Therefore, the investigation of various metallic plates including stainless steel, brass, and aluminum with their thicknesses of 76 μm on the displacement of BIPEDU has studied. To examine the displacement, all PE-MBLCs and BIPEDUs were su...
