Piezoelectric sensor element with at least two single crystal elements |
摘要 |
Individual single crystal elements stacked one above the other are aligned with their optical (Z) axes parallel to each other, and are provided with contact electrodes on opposite surfaces normal to their electrical (X) axes. Contact electrodes of the same polarity are conductively connected by two bridge electrodes that are applied to opposite sides of the assembled stack of individual crystal elements in the form of a conductive coating, and are provided with a lead leaving the sensor element. Contact electrodes of the opposite polarity are recessed in the vicinity of the bridge electrode serve the other polarity.
