  text: Hydrothermal method enables to synthesize high quality piezoelectric materials.
    To shorten the reaction time and to get higher quality materials, we propose an
    ultrasonic irradiation to the solution during the hydrothermal method. We named
    it ultrasonic assisted hydrothermal method (UAHTM). We have synthesized lead-free
    piezoelectric material and PZT thin film and the effect of UAHTM have been confirmed.
    In this study, we tried to improve UAHTM. First, to generate powerful and stable
    ultrasonic irradiation at high temperature on UAHTM, we developed a new transducer
    using LiNbO3 single crystal. Second, to prevent contamination to the materials,
    A Teflon cover on the tip of transducer was attached.

  text: 'A hydrothermal method utilizes a crystallization process in the solution
    so that the pure and high-quality powders can be realized. Sintering from the
    hydrothermal KNbO3 and NaNbO3 powders, a high-dense lead-free piezoelectric (K,Na)NbO3

  text: '[$Li_x(Na_0.52K_0.48)_1-x]NbO_3 (0 \leq x \leq 0.091)$ ceramics were synthesized
    using hydrothermal powders and the lithium doping content was controlled to optimize
    their piezoelectric properties. The raw KNbO$_3$ and NaNbO$_3$ powders were obtained
    separately by a hydrothermal method and LiNbO$_3$ powders were prepared by milling
    a commercial LiNbO$_3$ single crystal. These powders were mixed with ethanol at
    a molar ratio LiNbO$_3$: ($Na_0.52K_0.48$)NbO$_3 = x : 1-x$. The synthesized powders
    were sintered at 1060--1120 $\,^{\circ}$C for 2 h. We succeeded in obtaining highly
    dense [$Li_x(Na_0.52K_0.48)_1-x]NbO_3$ ceramics using hydrothermal powder. The
    X-ray diffraction patterns revealed that the crystal phase changed from orthorhombic
    to tetragonal at around x = 0.06. At this morphotropic phase boundary (MPB), the
    c/a ratio changed from 1.016 to 1.024 and the highest piezoelectric constant was
    obtained with the chemical component of [$Li_x(Na_0.52K_0.48)_1-x]NbO_3$. The
    obtained piezoelectric properties were as follows: $k_33 = 0.51, \epsilon 33^T/
    \epsilon _0 = 836$ , $c_33^E = 46$ GPa, $d_33 = 203$ pC/N, and $T_c = 482 $\,^{\circ}$C$.'

  text: Piezoelectric inertia motors, also known as ``stick-slip-drives'', use the
    inertia of a body to drive it by means of a friction contact in small steps. While
    these steps normally involve stiction and sliding, the motors can also operate
    in ``slip-slip'' mode without any phase of static friction. In this contribution,
    a one degree of freedom model of an inertia motor driven by an ideal actuator
    is analysed. Start-up and constant velocity operation of the motor are investigated
    and appropriate quantities to compare ``stick-slip'' and ``slip-slip'' operation
    are determined. Different aspects such as velocity, uniformity of motion, load
    capacity, robustness, efficiency, and wear are considered. The analysis allows
    both modes to be applied advantageously in different applications and can widen
    the field of application of piezoelectric inertia motors. Motor designers are
    enabled to choose the appropriate mode of operation and the best drive parameters
    for their individual applications.

  text: The multi-objective optimal design of a piezoelectric sandwich ultrasonic
    transducer is studied. The maximum vibration amplitude and the minimum electrical
    input power are considered as optimization objectives. Design variables involve
    continuous variables (dimensions of the transducer) and discrete variables (material
    types). Based on analytical models, the optimal design is formulated as a constrained
    multi-objective optimization problem. The optimization problem is then solved
    by using the elitist non-dominated sorting genetic algorithm (NSGA-II) and Pareto-optimal
    designs are obtained. The optimized results are analyzed and the preferred design
    is proposed. The optimization procedure presented in this contribution can be
    applied in multi-objective optimization problems of other piezoelectric transducers.

  text: The paper presents the results of numerical and experimental investigation
    of cylindrical piezoelectric actuator used for achieving independent three degrees
    of freedom oscillations of the contact point. The design of actuator based on
    a hollow piezoelectric cylinder mounted on a metal rod. The piezoceramic cylinder
    has a radial polarization and special configuration of the electrodes that cover
    inner and outer surface of the cylinder. The main advantage of actuator's design
    is that solid metallic rod operates as a part of inner electrode of the cylinder
    and a stator of actuator. The geometry of piezoelectric actuator was adopted to
    reach resonance of oscillations for the first longitudinal mode and the third
    flexural mode at same frequency. The actuator is designed to move positioned object
    through contact point which is located on the top of the rod. The optimal topology
    of electrodes was found to achieve longitudinal and flexural oscillations of the
    actuator in two perpendicular planes. Three degrees of freedom of the positioning
    object can be achieved and control of the system can be implemented by applying
    different excitation schemes and regimes. The numerical simulation and experimental
    study of piezoelectric actuator was performed. Impedance of actuator was analyzed
    under different excitation regimes. The results of numerical modeling and experimental
    study were compared. Recommendations for the further development of this type
    of actuator are given.

  text: In this study, we report some improvements in a hydrothermal method for lead-free
    piezoelectric powders and the performance of the sintered (K$_{0.48}$Na$_{0.52}$)NbO$_{3}$
    ceramics. To increase the obtained powder weight per source solution volume, the
    hydrothermal reaction conditions were modified. This improvement is important
    for mass production; however, it resulted in a larger particle size dispersion.
    Therefore, we examined to introduced the ball milling process that is useful for
    dense (K$_{0.48}$Na$_{0.52}$)NbO$_{3}$ ceramics. When a large amount of powder
    was obtained, it took a long time to eliminate the residual alkaline ions in the
    hydrothermal powders by a washing process. Therefore, a neutralization was conducted
    in the powder washing process. Using this powder, a solid solution of (K,Na)NbO$_{3}$ceramics
    was synthesized. The relative density was successfully increased. Concerning the
    electrical properties, the relative permittivity was improved, and the piezoelectric
    constant d$_{33}$ was also increased from 114 to 130 pC/N.

  text: Es wird eine Anordnung zur mehrdimensionalen Messung von Schwingungen eines
    Objektes vorgeschlagen, umfassend ein Vibrometer und eine erste Ablenkeinheit,
    mittels welcher der Messstrahl des Vibrometers in wenigstens zwei erste Raumrichtungen
    ablenkbar ist, sowie wenigstens eine zweite Ablenkeinheit, mittels welcher der
    aus einer der wenigstens zwei ersten Raumrichtungen auf eine zweite Ablenkeinheit
    eintreffende Messstrahl derart ablenkbar ist, dass ein Messpunkt des Objekts aus
    einer ersten Raumrichtung und wenigstens einer zweiten Raumrichtung oder wenigstens
    zwei zweiten Raumrichtungen damit erfassbar ist. Bei dem zum Betrieb der Anordnung
    vorgesehenen Verfahren wird der Messstrahl eines Vibrometers in wenigstens zwei
    erste Raumrichtungen abgelenkt, woraufhin wenigstens ein Messstrahl einer ersten
    Raumrichtung ein zweites Mal derart abgelenkt wird, dass ein Messpunkt des Objekts
    aus einer ersten Raumrichtung und wenigstens einer zweiten Raumrichtung oder wenigstens
    zwei zweiten Raumrichtungen erfasst wird, insbesondere so dass die zu untersuchenden
    Bewegungskomponenten in den Messsignalen, welche entlang der ersten und zweiten
    Raumrichtungen gewonnen werden, enthalten sind. The arrangement has a first deflecting
    unit (3) for deflecting a measuring beam of a vibrometer (2) in spatial directions
    (4-6, 4-6). Second and third deflecting units (7, 8) deflect the beam arriving
    from one of the spatial directions such that a measuring point (9) of an object
    (1) is detectable with the beam from the spatial direction or the spatial directions.
    The first deflecting unit is designed as a scanning unit, where the measuring
    point is detected by the scanning unit. A measuring instrument measures focus
    quality and is connected to actuators for adjustment of the focus quality. An
    independent claim is also included for a method for multidimensional measurement
    of oscillations of an object.

  text: The hydrothermal method enables the production of high-quality piezoelectric
    materials. In this study, we propose to irradiate the reaction solutions with
    ultrasonic power during the hydrothermal method to obtain a shorter reaction time
    and a smooth film surface. A high-pressure reaction container for the ultrasonic
    transducer was newly developed, and the ultrasonically-assisted hydrothermal method
    was examined by using this container. The effect of ultrasonic assist on the synthesis
    of lead-zirconate-titanate (PZT) thin films and (K,Na)NbO$_{3}$ powders was verified.
    Thicker PZT film, thickness around 10 ${\mu}$m, could be obtained in one process,
    and (K,Na)NbO$_{3}$ powder was synthesized in half the previous reaction time.

  text: Direct ultrasound irradiation is advantageous to increase the efficiency of
    the hydrothermal method which can be used for the production of piezoelectric
    thin films and lead free piezoelectric ceramics. To apply ultrasound directly
    to the process transducer prototypes were developed regarding the boundary conditions
    of the hydrothermal method. LiNbO$_{3}$ and PIC 181 were proven as feasible materials
    for high temperature resistant transducers ($\geq 200^\circ C$). Resistance of
    the transducers horn against the corrosive mineralizer was achieved by using Hastelloy
    C-22. The efficiency of the ultrasound assisted hydrothermal method depends on
    the generated sound field. Impedance and sound field measurements have shown that
    the sound field depends on the filling level and the position and design of the
    transducer.

  text: In the modeling of piezoelectric Langevin transducers using usual transfer
    matrix methods, some simplifications have been adopted. This leads to reduction
    of the model quality. A mixed transfer matrix method is employed in the modeling
    of Langevin transducers, where the pre-stressed bolt is modeled as a separate
    four-pole element, which is connected to other elements in parallel. Based on
    the mixed transfer matrix method, the four (six)-pole element description of the
    piezoelectric Langevin transducer is built up and the total transfer matrix relation
    is derived. The resonance frequencies of the transducer are calculated and then
    measured using the impedance analyzer (HP4192). Experimental result shows that
    the mixed transfer matrix method has better modeling quality than the usual transfer
    matrix method for the vibration analysis of piezoelectric Langevin transducers.

  text: Piezoelectric materials find wide application in technical systems. Most often,
    a combination of piezoelectric and other materials is advantageous. The position
    and the amount of the piezoelectric material within the overall system depends
    on various aspects like maximum mechanical output to the load, maximum electromechanical
    efficiency of the system, maximum utilization of the piezoelectric material, minimum
    self-heating of the piezoelectric material, and controllability of the system,
    which might be key aspects for the optimisation of the system design. For a composite
    longitudinal vibrator (bolted Langevin transducer), which is a base for many technical
    applications, this contribution shows in detail, how above mentioned aspects depend
    on the position and volume of the piezoelectric material related to the mode shape.

  text: 'Piezoelectric inertia motors have a simple construction and are controlled
    by a single driving signal. This allows for miniaturization and low cost production.
    One of the main questions to be answered during the design process of a piezoelectric
    inertia motor is which electrical excitation signal yields optimum motor characteristics.
    Three signals and their variants are widely used in literature: sawtooth, parabolic
    and cycloidic signals. It can be shown that neither of these can drive the motor
    at its maximum possible velocity in non-resonant operation. Within this paper
    we propose to use a rigid body model of a simple inertia motor to predict the
    motor characteristics depending on the movement pattern of the driving element.
    Advantages and disadvantages of three different drive signals that maximize the
    motor velocity are discussed.'

  text: Piezoelectric inertia motors make use of the inertia of a slider to drive
    the slider by friction contact in a series of small steps which are generally
    composed of a stick phase and a slip phase. If the best electrical drive signal
    for the piezoelectric actuator in an inertia motor is to be determined, its dynamical
    behaviour must be known. A classic dynamic lumped parameter model for piezoelectric
    actuators is valid only in resonance and, therefore, is not suitable for modelling
    the actuator in an inertia motor. A reduced dynamic model is used instead. Its
    parameters are identified using a step response measurement. This model is used
    to predict the movement of the actuator in response to a velocity-optimized signal
    introduced in a separate contribution. Results show that the model cannot represent
    the dynamical characteristics of the actuator completely. For determining voltage
    signals that let piezoelectric actuators follow a calculated movement pattern
    exactly, the model can, therefore, only be used with limitations.

  text: 'Piezoelektrische Trägheitsmotoren nutzen die Trägheit einer bewegten Masse,
    um diese in kleinen Schritten durch abwechselnde Haft- und Gleitphasen voranzutreiben.
    Eine Kernfrage bei der Entwicklung eines piezoelektrischen Trägheitsmotors ist,
    welches elektrische Ansteuersignal für das gewünschte Motorverhalten optimal ist.
    Das elektrische Signal führt zu einer Bewegung des piezoelektrischen Aktors und
    damit der Antriebsstange, die den reibschlüssigen Vortrieb bewirkt. Entsprechend
    wird diese Fragestellung in zwei Teilen untersucht: Anhand eines Starrkörpermodells
    werden zunächst Bewegungsverläufe für die Antriebsstange ermittelt, mit denen
    die maximale Geschwindigkeit erreicht wird. Dabei werden drei Antriebsmodi identifiziert.
    Mit allen kann eine höhere Geschwindigkeit als mit der heute häufig verwendeten
    Sägezahnanregung erreicht werden. Anschließend wird ein einfaches dynamisches
    Modell eines piezoelektrischen Aktors genutzt, um die notwendigen elektrischen
    Ansteuersignale für die verschiedenen Antriebsmodi zu bestimmen. Es zeigt sich,
    dass das gewählte einfache Modell hierzu nur bedingt geeignet ist.'

  text: A model based design approach for improved piezoelectric inertia motors is
    presented. Three velocityoptimized movement patterns for the driving body have
    been derived. The influence of the motor parameters and the process of designing
    an application specific motor with maximum velocity are shown. A simple dynamic
    model of the piezoelectric actuator is used to calculate the voltage signal for
    achieving the desired movement pattern. Observed distortions of the optimum pattern,
    their influence on the motion of the driven body and different methods to reduce
    them are discussed.

  text: Dieser Beitrag fasst die bekannten analytischen Berechnungsmethoden für piezoelektrische
    Ultraschallverbundschwinger zusammen und gibt anhand typischer Beispiele Anleitungen
    zur Lösung theoretischer und technischer Fragen bei deren Entwicklung. Zunächst
    werden die passiven, in der Regel metallischen Komponenten von Verbundschwingern
    als Stab- oder Plattensysteme mit homogen verteilten Feder-, Masse und Dämpfungseigenschaften
    beschrieben. Hier breitet sich die Schwingungsenergie in Form stehender und fortschreitender
    Wellen zum akustischen Verbraucher hin aus. Es folgt eine gleichwertige und schaltungstreue
    Darstellung durch elektrische oder mechanische Vierpole, die für den Entwicklungsingenieur
    leichter zu handhaben sind und in Netzwerken direkt mit Masons Ersatzschaltung
    des piezoelektrischen Wandlers gekoppelt werden können. Danach werden die wichtigsten,
    messtechnisch zugänglichen Parameter anhand eines in Resonanznähe zulässigen Ersatzmodells
    mit konzentrierten elektrischen bzw. mechanischen Komponenten definiert. Als Schwerpunkt
    wird anschließend deren analytische Berechnung und messtechnische Verifizierung
    an typischen Beispielen demonstriert. Es folgen wichtige technische Informationen
    über Frequenzkorrekturen, Schallgeschwindigkeitsdispersion, Leistungs- und Belastbarkeitsgrenzen
    der Komponenten und andere wertvolle praktische Hinweise.
