  • Solder Material for Fastening an Outer Electrode on a Piezoelectric Component and Piezoelectric Component Comprising a Solder Material
    Publication number: 20120280593
    Abstract: A solder material can be used for fastening an outer electrode on a piezoelectric component. The solder material contains tin as the main constituent and at least one addition from the group of cobalt, tungsten, osmium, titanium, vanadium, iron and rare earth metals. A piezoelectric component includes such a solder material. The solder material is applied by means of a base metallization.

  • Piezo Actuator in Multi-Layered Construction
    Publication number: 20120019107
    Abstract: A multilayer piezo actuator is specified, in which piezoelectric layers and electrode layers are arranged to form a stack. Electrical contact is made with the electrode layers via two external electrodes which consist of wires which are woven with one another. The external electrodes are in this case connected over their entire area to the side surfaces of the stack. A method is also specified for fitting an external electrode.

  • Method for operating a piezoelectric element
    Patent number: 8089197
    Abstract: A method for operating a piezoelectric element is disclosed. A first voltage is applied to a piezoelectric element and produces a first deflection of the piezoelectric element with a travel. An electrical discharge of the piezoelectric element after the application of the first voltage results in a first contraction of the piezoelectric element by a first compression. After the first contraction, a second voltage is applied to the piezoelectric element, whose polarity is opposite that of the first voltage and causes a further contraction of the piezoelectric element by a second compression. Repeated application of the first voltage after the electrical discharge of the applied second voltage results in a deflection of the piezoelectric element with the same travel.

  • Piezoelectric Actuator of a Multilayer Design and Method for Fastening an Outer Electrode in a Piezoelectric Actuator
    Publication number: 20110215674
    Abstract: A piezoelectric actuator of a multilayer design includes outer electrodes that are fastened by means of a bonding layer applied by thermal spraying. For example, the outer electrodes are formed as a woven wire fabric. Furthermore, a method for fastening an outer electrode in a piezoelectric actuator is specified.
