摘要： The invention relates, inter alia, to an additional contact (30) for a piezoelectric component (10) in the form of a multilayer structure and to a corresponding component, wherein the piezoelectric component (10) is formed by a stack (17) of alternating piezoelectric ceramic layers and electrode layers. The additional contact (30) has a contact element (31) with a contact zone (33) for connection to an electrical connecting element (20) and with a fastening zone (34) for connection to a metallized part (15, 16). In order to minimize harmful tensile/pressure loads in the additional contact (30), the additional contact (30), especially the contact element (31), is shaped so as to allow for a load distribution of the critical tensile loads, for example by means of at least one bend (32) in the contact element (31).

摘要： The invention relates to a green body, a piezoelectric component (10) and a method for the production of a piezoelectric component (10) in the form of a multilayer structure having at least one piezoelectric ceramic layer (11) and at least one electrode layer (12) connected to the piezoelectric ceramic layer (11). A green body is initially produced, wherein at least one electrode layer (12) is placed on at least one piezoelectric green ceramic layer. The resulting stack (16) for producing the piezoelectric component (10) is then subjected to at least one additional finishing step, for instance a sintering step. In order to produce piezoelectric components (10) with a long service life and high reliability, the at least one piezoelectric ceramic layer (11) is not configured as an individual layer but in the form of a first ceramic partial layer (13) and at least a second ceramic partial layer (14, 15). The ceramic partial layers (13, 14, 15) advantageously have a thickness which is smaller than the thickness of the piezoelectric ceramic layer (11) after carrying out the finishing step. In the production of the green body, a first green ceramic partial layer that can carry an electrode layer (12) is advantageously placed on at least one second green ceramic partial layer that does not carry an electrode layer.

摘要： The invention relates, inter alia, to a piezoelectric component (10) in the form of a multilayer structure, wherein a piezoelectric ceramic layer (11) and an electrode layer (12, 13) are always alternatingly superimposed to form a stack (18), wherein each electrode layer (12, 13) extends at least in certain areas to at least one side surface (19) of the stack (18). In order to protect the component (10) against short circuits and flashovers, a passivation (20) is provided on the at least one side surface (19). In order to ensure that bonding of said passivation (20) on the surface (19) of the component (10) always remains unaltered, especially when cracks emerge in the ceramic layers (11), the passivation (20) is formed by a passivation material having a tearing strength that is smaller than the bonding strength of the passivation material on the surface (19) of the component (10). The invention also relates to advantageous passivation materials, wherein said materials can be, for instance, a polyurethane, a fluorine-silicone rubber and the like.
