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.","lang":"eng"}],"user_id":"55222","quality_controlled":"1","publisher":"AIP","author":[{"last_name":"Lucinskis","full_name":"Lucinskis, Raimundas","first_name":"Raimundas"},{"first_name":"Dalius","full_name":"Mazeika, Dalius","last_name":"Mazeika"},{"first_name":"Tobias","full_name":"Hemsel, Tobias","last_name":"Hemsel","id":"210"},{"last_name":"Bansevicius","first_name":"Ramutis","full_name":"Bansevicius, Ramutis"}],"keyword":["dielectric polarisation","piezoceramics","piezoelectric actuators"],"publication":"AIP Conference Proceedings","volume":1433,"status":"public","date_created":"2019-05-13T10:56:30Z"},{"abstract":[{"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.","lang":"eng"}],"title":"Development of a biomedical tissue differentiation system using piezoelectric actuators","user_id":"55222","author":[{"last_name":"Uribe","full_name":"Uribe, David Oliva","first_name":"David Oliva"},{"full_name":"Stroop, Ralf","first_name":"Ralf","last_name":"Stroop"},{"id":"210","last_name":"Hemsel","full_name":"Hemsel, Tobias","first_name":"Tobias"},{"last_name":"Wallaschek","full_name":"Wallaschek, Jörg","first_name":"Jörg"}],"quality_controlled":"1","publication":"Frequency Control Symposium, 2008 IEEE International","department":[{"_id":"151"}],"keyword":["biomedical measurement","brain","cancer","neurophysiology","phantoms","phase locked loops","piezoelectric actuators","surgery","tactile sensors","transfer functions","tumours","PLL","biomedical tissue differentiation system","brain tumor resection","frequency control","frequency shift","gel-phantom","high sensitivity actuator-sensor system","neurosurgery","phase-locked loop","piezoelectric actuators","piezoelectric bimorph","self-oscillating circuit","sensor sensitivity","tactile differentiation","tactile sensor system","transfer function","tumor boundary","visual differentiation","Biomedical measurements","Circuits","Frequency control","Neoplasms","Neurosurgery","Phase locked loops","Piezoelectric actuators","Surges","Transfer functions","Voltage"],"publication_identifier":{"issn":["1075-6787"]},"status":"public","date_created":"2019-04-29T13:07:39Z","_id":"9576","date_updated":"2022-01-06T07:04:16Z","doi":"10.1109/FREQ.2008.4622963","type":"conference","citation":{"short":"D.O.
