Structure for improving flexoelectric effect of ceramic chip and manufacturing method
The invention discloses a structure for improving the flexoelectric effect of a ceramic chip and a manufacturing method. Relates to the field of flexoelectricity, and provides a structure designed by the method. The structure comprises a ceramic sheet, electrodes and a middle isolation layer. The preparation method of the ceramic sheet comprises the following steps: preparing a thin ceramic green body from raw material powder under certain process conditions, and sintering the green body to obtain the compact ceramic sheet. The metal electrode only covers one part of the ceramic, an electrode is led out from one end, and a space is reserved at the other end, so that a parallel structure is formed in the later period. The design of the middle isolation layer prevents the upper layer and the lower layer from counteracting each other due to inconsistent polarization directions when the flexoelectric effect is generated, and meanwhile, the material selected by the middle isolation layer provides certain flexibility for the overall structure, so that a basis is provided for good operation of a flexoelectric device.
本发明公开了一种提高陶瓷片挠曲电效应的结构及制造方法。涉及挠曲电领域，提供了该方法设计的结构包括陶瓷薄片、电极和中间隔离层。陶瓷片是将原料粉体在一定的工艺条件下，制备出较薄的陶瓷生坯，再将生坯进行烧结，得到致密的陶瓷薄片。金属电极只覆盖陶瓷的一部分，且在一端引出电极，另一端留有空余，这样的设计是为了后期形成并联结构。中间隔离层的设计是避免挠曲电效应产生的时候，上下层由于极化方向的不一致而导致的相互抵消，同时中间隔离层选择的材料为总体结构提供一定的柔韧性，为挠曲电器件的良好运行提供基础。
