text: With enhancing digitalization, condition monitoring is used in an increasing
number of application fields across various industrial sectors. By its application,
increased reliability as well as reduced risks and costs can be achieved. Based
on different approaches, technical systems are monitored and measured data is
analyzed to enable condition-based or predictive maintenance. To this end, machine
learning approaches are usually implemented to diagnose the health states or predict
the health index of the monitored system. However, these trained models are often
black-box models, not intuitively explainable for a human. To overcome this shortcoming,
a model-based approach based on physics is developed for piezoelectric bending
actuators. Such a model enables a transparent representation of the system. Moreover,
the model-based approach is extended by a parameter-estimation to account for
sudden changes in behavior e. g. caused by occurring cracks.

text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. These motors can operate in
``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
a Coulomb friction model is sufficient in many cases, but numerical simulation
requires microscopic time steps. This contribution proposes a much faster simulation
technique using one evaluation per period of the excitation signal. The proposed
technique produces results very close to those of timestep simulation for ultrasonics
inertia motors and allows direct determination of the steady-state velocity of
an inertia motor from the motion profile of the driving part. Thus it is a useful
simulation technique which can be applied in both analysis and design of inertia
motors, especially for parameter studies and optimisation.

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: "EN: Although the use of new actuator technologies is quite enthusiastic,
the realization of innovative systems based on these principles fails because
of doubts in dependability. Until now, new working principles for actuators have
not been systematically investigated in the means of dependability. Therefore
we developed a proceeding for a dependability-oriented evaluation of technologies.
This is shown in the case of shape memory alloy actuators. \r\nDE: Die Realisierung
von Systemen mittels innovativer Aktortechnologien scheitert oftmals an der Skepsis
gegenüber der Verlässlichkeit (Vertrauen in die zuverlässige und sichere Funktionalität
der Technologie). Diese liegt darin begründet, dass neue Aktortechnologien bzw.
die Integration von innovativen physikalischen Wirkprinzipen innerhalb neuer Aktorkonzepte
bisher noch nicht systematisch im Kontext der Verlässlichkeit untersucht werden.
Daher haben wir ein Vorgehen zur verlässlichkeitsorientierten Technologiebewertung
entwickelt. Neben der detaillierten Darstellung des Vorgehensmodells wird es exemplarisch
anhand von Formgedächtnislegierungen zur Entwicklung innovativer Antriebslösungen
angewendet."

text: 'In neurosurgery, delineation of tumor boundaries during resection of brain
tumors is of substantial relevance. During operation distinction between tumor
and healthy tissue rely on the abilities of the surgeon based on visual and tactile
differentiation. In this paper a high sensitivity actuator-sensor system using
a piezoelectric bimorph is presented. Frequency shift and transfer function of
the bimorphpsilas voltages are detected and evaluated. Sensorpsilas sensitivity
is evaluated using two frequency controls strategies: A phase-locked loop (PLL)
and a self-oscillating circuit. Results of measurements conducted on gel-phantoms
are presented and discussed.'
