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 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.'
