    • The invention relates to an actuator unit for a fuel injection valve of an internal combustion engine of a vehicle. The actuator unit comprises an electronic component (10) formed as a stack. Said component (10) comprises a plurality of electrode layers and a plurality of material layers which react to the application of an electric field, the material and electrode layers being arranged alternately. The component (10) also comprises two outer electrodes (11, 12) which are electrically connected to respective electrode layers on at least one circumferential side of the component (10). In addition, the actuator unit comprises a piezoelectric sensor (20) that is coupled to the component (10) in a force-fitting manner, in the stroke direction of the component (10). When the component (10) is in operation, the sensor (20) detects a force (F) generated by the component, which can be detected as a voltage or charge between two electrodes (24, 25) arranged on opposing end faces (22, 23) of a sensor element (21). The electrodes (24, 25) are deposited from an electrically conductive material directly onto at least the end faces (22, 23) of said sensor element (21).

    • The invention relates to a method for producing an electronic structural element as a stack (1), formed from a plurality of material layers (2) that react to the application of an electric field, and a plurality of first and second electrode layers (3, 4), each material layer (2) being arranged alternately between two of the electrode layers (3, 4). At least one first and one second contacting structure (13, 14) are applied to at least one stack peripheral region (5, 6) such that each first electrode layer (3) is electrically contacted via the first contacting structure (13) and each second electrode layer (4) is electrically contacted via the second contacting structure (14). In a first step, a stack (1) is produced in which the first electrode layers (3) protrude beyond the at least one stack peripheral region (5, 6), and the second electrode layers (4) come to lie, within said material layers (2), at a distance from the at least one stack peripheral region (5, 6). The first contacting structure (13) is then directly applied to the at least one stack peripheral region (5, 6), said first electrode layers (3) that protrude out of the at least one stack peripheral region (5, 6) being electrically-conductively embedded into the first contacting structure (13). Following this, the second contacting structure (14) is produced by virtue of the first and second electrode layers (3, 4) being exposed on the at least one stack peripheral region (5, 6), before a solvent-free insulation structure (15) is produced by means of an additive method which electrically insulates the first electrode layers (3) from the at least one stack peripheral region (5, 6). In a final step, electrically-conductive material is applied to the prepared stack peripheral region (5, 6) in order to form the second contacting structure (14).
    • 公开了一种形成具有堆叠的电子结构元件的方法,所述堆叠包括交替地与材料层排列的第一和第二电极层。 形成堆叠,其中第一电极层突出超过堆叠的第一横向侧,并且第二电极层与第一侧面径向向内间隔开。 接触每个第一电极层的第一接触结构直接施加到堆叠的第一侧,该接触结构以这种突出的第一电极层以导电方式嵌入。 通过在堆叠的第二侧暴露第一和第二电极层来形成第二接触结构,通过添加方法形成电绝缘第一电极层的无溶剂绝缘结构,并且将导电材料施加到 无溶剂的绝缘结构,以形成接触每个第二电极层的第二接触结构。
