Abstract
(EN) Provided are a sensor and a production method therefor, a panel, and a recognition device. The sensor comprises a substrate, a first electrode layer disposed on the substrate, a second electrode layer disposed on the side of the first electrode layer distant from the substrate, and a piezoelectric layer disposed between the first electrode layer and the second electrode layer. The orthographic projection, on the substrate, of the top surface of the piezoelectric layer away from the first electrode layer covers the orthographic projection, on the substrate, of the bottom surface of the piezoelectric layer facing the first electrode layer.
(FR) L'invention concerne un capteur et son procédé de production, un panneau et un dispositif de reconnaissance. Le capteur comprend un substrat, une première couche d'électrode disposée sur le substrat, une seconde couche d'électrode disposée sur le côté de la première couche d'électrode à distance du substrat, et une couche piézoélectrique disposée entre la première couche d'électrode et la seconde couche d'électrode. La projection orthographique, sur le substrat, de la surface supérieure de la couche piézoélectrique à l'opposé de la première couche d'électrode recouvre la projection orthographique, sur le substrat, de la surface inférieure de la couche piézoélectrique faisant face à la première couche d'électrode.
(ZH) 提供了一种传感器及其制备方法、面板、识别装置,该传感器包括:衬底、设置于所述衬底上的第一电极层、设置于所述第一电极层远离所述衬底的一侧的第二电极层、以及设置于所述第一电极层和所述第二电极层之间的压电层。压电层背离所述第一电极层的顶表面在所述衬底上的正投影覆盖其面向所述第一电极层的底表面在所述衬底上的正投影。
