    摘要: The invention relates to a method for producing piezoelectric actuators (1) from a material block, comprising firstly the provision of the material block (100) made of a plurality of piezoelectric layers (10) stacked one above the other, wherein the respective surfaces (O10) of the layers are arranged one above the other, and furthermore the provision of a cutting device (200) for introducing at least one cut (S1, S2, S3) into the material block. At least one actuator is separated individually from the material block by moving the material block (100) or the cutting device (200) in relation to each other in such a manner that the material block is cut by the cutting device, wherein a cutting direction (R1, R2, R3) of the cutting device runs in the respective plane of the surfaces (O10) of the piezoelectric layers (10) of the material block.

    摘要: A multilayered electroactive polymer (EAP) device and a method of manufacturing the same is provided. The multilayered EAP device includes a plurality of unit layers. Each unit layer includes an EAP layer (111-118) formed of an electroactive polymer (EAP), a protecting layer (121-128) configured to prevent a material from penetrating into the EAP layer, and an active electrode (131-138) formed using a conductive material. The protecting layer may be formed below the active layer or above the active layer. The active electrode may be interposed between two protecting layers.

    摘要: [Object] To provide a fluid conveyance device having a simple and compact structure and conveying efficiently a fluid.
    [Solving Means] A fluid conveyance device includes a substrate 10, and a disk-like piezoelectric element 20 arranged in a bendable fashion on the substrate. A plurality of circular concentric segment electrodes 23a-23e are formed on the piezoelectric element 20, and are provided with voltages E1-E4 with phases thereof shifted. A ring wavy deformation is thus caused on the piezoelectric element 20. A ring pocket caused between the piezoelectric element 20 and the substrate 10 is moved in a radial direction, conveying a fluid from an outer circular portion to a central portion and discharging the fluid from the central portion.
