| 20080224570 | Transformer Arrangement Having a Piezoelectric Transformer - A transformer arrangement is specified which includes a piezoelectric transformer with a main body ( | 09-18-2008 |
| 20090278424 | PIEZOELECTRIC TRANSFORMER AND METHOD FOR PRODUCTION THEREOF - A piezoelectric transformer includes an input part and an output part. The input part and the output part are mechanically connected along a path that includes an insulating part. The insulating part includes a surface with a depression. In the input part, mechanical oscillations are generated using electrical voltages, and, in the output part, the mechanical oscillations are converted to electrical fields. | 11-12-2009 |
| 20100109488 | Piezoelectric Multilayer Component - A piezoelectric multilayer component has a base body with a stack of piezoceramic layers and electrode layers arranged one on top of the other in an alternating manner. Neighboring layers of the stack are braced against one another such that stresses run perpendicular to the stacking direction. | 05-06-2010 |
| 20100219724 | Ceramic Material, Method for Producing the Same, and Electro-Ceramic Component Comprising the Ceramic Material - A ceramic material includes lead zirconate titanate, which additionally contains Nd and Ni. | 09-02-2010 |
| 20100225205 | Piezoelectric Multilayer Component - A piezoelectric multilayer component includes a stack of piezoceramic layers and electrode layers arranged one above another. At least one piezoceramic layer is printed with a layer structured according to a predefined pattern in a piezoelectrically inactive zone of the stack. The structured layer has at least one connecting element by which piezoceramic layers that are adjacent in the stacking direction are mechanically connected to one another with a first strength. The structured layer has interspaces filled at least in part with piezoceramic material of the adjacent piezoceramic layers. The adjacent piezoceramic layers in the interspaces are mechanically connected to one another with a second strength, which is less than the first strength. | 09-09-2010 |
| 20100320876 | Piezoelectric Multilayer Component - A piezoelectric multilayer component has a stack of green piezoceramic layers arranged one on top of the other. A first electrode layer is applied onto a piezoceramic layer and contains a first metal. A structured sacrificial layer is applied onto a further piezoceramic layer, adjacent to the first electrode layer in the stacking direction, and contains a higher concentration of the first metal than does the first electrode layer. When the intermediate product is sintered, the first metal diffuses from the structured sacrificial layer to the first electrode layer and in the process leaves cavities which form a weak layer. | 12-23-2010 |
| 20110006644 | Piezoelectric Multilayer Component - A piezoelectric multilayer component includes a stack of piezoceramic layers, which are arranged one on top of the other, and electrode layers. The stack has a first area and a second area. The second area contains a disturbance material, which is used to make the second area less mechanically robust than the first area. | 01-13-2011 |
| 20110101829 | Piezoelectric Multilayer Component - A piezoelectric multilayer component includes a stack of green piezoceramic layers which are arranged one on top of the other. A first electrode layer is applied to a piezoceramic layer and contains a first metal. A second electrode layer is applied to a further piezoceramic layer and is adjacent to the first electrode layer in the stacking direction. The second electrode layer contains a higher concentration of the first metal than does the first electrode layer. | 05-05-2011 |
