text: Among various lead-free piezoelectric materials, (K,Na)NbO$_{3}$ is a very
promising candidate. In this study, (K,Na)NbO$_{3}$ ceramics were sintered from
mixed (K,Na)NbO$_{3}$ and NaNbO$_{3}$ powders prepared by hydrothermal reaction.
These two powders were mixed with distilled water in a KNbO$_{3}$/NaNbO$_{3}$
molar ratio of 1. After sintering the mixed powder, the solid solution of (Na,K)NbO$_{3}$
ceramics was obtained. The electrical properties such as the electromechanical
coupling factors k$_{p}$ and k$_{33}$, the mechanical quality factor, Q$_{m}$,
and the piezoelectric constant d$_{33}$ of the sintered (K,Na)NbO$_{3}$ ceramics
were 0.32, 0.48, 71 (radial mode), 118 ((33)mode), and 107 pC/N, respectively.

text: Self-optimizing systems are able to adapt their behavior autonomously according
to their current self-determined objectives. Unforeseen influences could lead
to dependability-critical behavior of the system. Methods are required which secure
self-optimizing systems during operation. These methods to increase the dependability
of the system should already be taken into consideration in the design process.
This paper presents a guideline for the dependability-oriented design of self-optimizing
systems, which integrates established classical methods like failure mode and
effects analysis as well as methods based on self-optimization. On the one hand
self-optimization is used to increase the dependability of the system by integrating
objectives like safety, availability, and reliability to the objectives of the
system. On the other hand methods are required to ensure the self-optimization
itself. As basis for this guideline serves the principle solution of the system.
The six phases of the guideline extend the design process and lead to an enhanced
principle solution. Additionally, the guideline illustrates phases to implement
and validate the self-optimizing system. The proposed guideline is applied to
an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
function modules.

text: Die Entwicklung piezoelektrischer Tr{\"a}gheitsmotoren basiert derzeit auf
Erfahrungswissen und Prototypenbau. Es existiert kein allgemeines Modell und keine
Methodik f{\"u}r die systematische Entwicklung dieser Motoren. In diesem Beitrag
stellen wir einen Ansatz zur Entwicklung einer solchen Methodik und den von uns
aufgebauten Versuchsmotor vor. Der Motor ist modular aufgebaut; er besteht im
Wesentlichen aus einer piezoelektrischen Antriebseinheit, einem Antriebsstab und
dem zu bewegenden Schlitten. Eine wesentliche Aufgabe bei der modellbasierten
Entwicklung von Tr{\"a}gheitsmotoren ist die hinreichende Beschreibung des dynamischen
Verhaltens der Antriebseinheit. Um ein geeignetes Modell zu finden, bzw. um nachzuweisen,
dass einfache parametrische Modelle gen{\"u}gen, wird die Antriebseinheit des
Motors detailliert untersucht. Es zeigt sich, dass der derzeitige Aufbau eine
Reihe von Nachteilen aufweist, die durch eine teilweise Neukonstruktion der Antriebseinheit
beseitigt oder zumindest entsch{\"a}rft werden k{\"o}nnen.

text: Die Integration von Selbstoptimierung in mechatronische Systeme beinhaltet
sowohl Risiken als auch Potenziale für die Verlässlichkeit. Die Risiken entstehen
durch die Selbstoptimierung in den komplexen Systemen, da das Systemverhalten
nur begrenzt im Voraus vorhersehbar ist. Daher wurde innerhalb des Sonderforschungsbereichs
614 ''Selbstoptimierende Systeme des Maschinenbaus" ein mehrstufiges Verlässlichkeitskonzept
entworfen, welches das Ziel Verlässlichkeit stärker im Zielsystem verankert. In
diesem Beitrag wird zum einen das erarbeitete Verlässlichkeitskonzept und zum
anderen die Anwendung dieses Konzepts innerhalb des aktiven Spurführungsmoduls
eines schienengebundenen Fahrzeugs vorgestellt. Um Programmierfehler auszuschließen
wurde das Verlässlichkeitskonzept modelliert und über Model Checking verifiziert.
Anhand von Simulationsergebnissen wird gezeigt, wie durch das mehrstufige Verlässlichkeitskonzept
auf einen Ausfall eines Wirbelstromsensors des aktiven Spurführungsmoduls reagiert
werden kann.

text: A simple pre-stress estimate method of Langevin transducers is studied. The
measurement setup consists of a capacitor, an impedance converter and a voltmeter.
Based on the piezoelectric equation and the basic circuit theory, the mathematical
expression between the pre-stress and the voltage across the capacitor is derived.
The pre-stress level can then be calculated out of the measurement of the capacitor
voltage. In order to evaluate the precision of this method, a force washer is
used to measure the pre-stress of the Langevin transducer. The result shows the
pre-stress level obtained from this method is 30-40\% higher than the pre-stress
level measured by the force washer. This method is simple and can be used to estimate
the pre-stress of various Langevin transducers. The precision of this method can
be raised if d33 is identified under different pre-stress levels.

text: Ultrasonic hyperthermia and thermo-ablation are two promising alternatives
for local overheating of deep-seated human tumours. After a short characterisation
of the two techniques and the identification of the main parameters, results of
an analytical theory of local heat up, cooling, and heat diffusion are presented.
The theory is based on a spherical model for hyperthermia with a critical thermal
dose and on a cylinder-symmetrical model for thermo-ablation with a critical temperature
threshold for thermal toxicity and cell death through coagulative necrosis. Two
representative hard ware concepts are discussed. The hyperthermia applicator consists
of a MHz transducer, which rotates concentrically in a water filled capsule with
acoustically transparent window, and radiates collimated or focussed ultrasound
under 45$\,^{\circ}$ into a concentric target area of nearly spherical symmetry.
The applicator for thermo-ablation is a MHz transducer which radiates high intensity
focussed ultrasound (HIFU) into "cigar shaped" target areas at the focal zone.
Typical therapy diagrams for both techniques are presented. They show therapeutic
target volumes as functions of the therapy time with the peak temperature or the
radiated acoustic power as parameters. These diagrams are discussed under consideration
of power requirement, maximal sound intensity, and power efficiency at close to
optimized frequency conditions.

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

text: 'Several positioning tasks demand translatory drive instead of rotary motion.
To achieve drives that are capable, e.g., to drive the sunroof of a car or to
lift a car''s window, multiple miniaturized motors can be combined. But in this
case many other questions arise: The electromechanical behavior of the individual
motors differs slightly, the motor characteristics are strongly dependent on the
driving parameters and the driven load, many applications need some extra power
for special cases like overcoming higher forces periodically. Thus, the bundle
of motors has to act well-organized and at last controlled to get an optimized
drive that is not oversized and costly.'

text: For devices having non-linear contact, load plays a fundamental role. Variations
in the characteristics of the load cause change in eigenfrequency and amplitude
of the vibration. In most technical applications, this unwanted behaviour is cancelled
by the use of control algorithms. However, multiple applications, like bond quality
monitoring or chemical and pressure sensors, have found that the load may be characterised
by interpreting the change in characteristics of a resonant vibrating device used
as a sensor. Surgical resection of tumours is a very difficult task. After localising
the tumour by the use of imaging techniques, the resection demands the surgeon
to decide where and what to resect based on visual and tactile differentiation
of tumour and healthy tissue. Exactness of this process could be enhanced if we
can provide the surgeon with a device capable of evaluating mechanical characteristics
of the tissue much more accurately than the surgeon himself can do. As the mechanical
characteristics of tumour and healthy tissue differ but slightly, the task is
to design a system with high sensitivity. Therefore, we have developed a resonant
actuator-sensor that allows the differentiation among distinct media that have
similar mechanical characteristics to tumour and healthy tissue using a piezoelectric
bimorph. The design is based on the detection and evaluation of frequency shift
and amplitude variation of the fundamental and higher harmonics using one layer
for the resonant excitation of vibration and the other one as the sensing element.

text: Many ultrasonic processes are based on the mechanical contact of oscillating
parts. Within ultrasonic machining (drilling, milling, grinding) micro impacts
lead to abrasion at the processed workpiece and hopefully do not damage the tool.
In ultrasonic motors ideally neither part gets worn. Thus the appropriate design
of contact partners as well as their kinematics is a substantial task during the
development of such devices. A first step to optimize contact mechanics is to
understand their behavior and dependencies on parameter variations, such as vibration
amplitude and pre-stress of the impacting parts. For a detailed understanding
models validated with convincing experimental data from measurements are absolutely
essential. This paper focuses on simple vibro-impact experiments which can be
used as benchmark data for future models. The setup of the experiment and first
experimental investigations are described in detail.

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.'

text: Penetration tests (Magness-Taylor, force/deformation, Kramer multiblade shear)
applied directly over the peel of the fruit are the most acceptable methods for
measuring firmness and turgidity of fruits and vegetables [1, 2]. To replace these
destructive and mechanical penetration methods by non-destructive ultrasonic measurements
implies a great advance in order to obtain fast studies about the state of the
fruit at the time of harvest, during storage, and in the distribution points.
Moreover, there are other advantages since this technique can be fast, non-destructive,
fully automated, and performed on-line [1]. Within this context, the objective
of this study was to examine the relationship between physico-mechanical characteristics
(oil-gland break stress, thickness and dehydration) and ultrasonic characteristics
in the ``Salustiana'' orange peel during the complete dehydration process of the
orange at ambient conditions. After a description of the measurement system [3],
the fruit selection procedure and the measurement protocol, we analyze the results
of the change of physico-mechanical and ultrasonic properties in the orange peel
and their change with storage time.

text: 'Surgical resection of brain tumours is a difficult task. To enhance surgery
results, a tactile sensor is wanted that gives better resolution and sensitivity
than the human tactile sense. The characteristics of resonant vibrating piezoelectric
elements change with varying load. This allows for calculation of mechanical load
parameters by measuring electrical quantities. Different setups of piezoelectric
sensors have been used to investigate soft materials. Finally, a piezoelectric
bimorph sensor gave good results for distinguishing tissue mimicking gel-phantoms
with different gelatine concentrations. '
