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."}],"citation":{"ieee":"F. Bo, L. Ting, and T.

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."}]},{"author":[{"first_name":"Thomas","last_name":"Müller","full_name":"Müller, Thomas"},{"first_name":"Florian","last_name":"Schiedeck","full_name":"Schiedeck, Florian"},{"id":"210","full_name":"Hemsel, Tobias","last_name":"Hemsel","first_name":"Tobias"}],"year":"2008","status":"public","title":"Verlässlichkeitorientierte Technologiebewertung innovativer Aktortechnologien am Beispiel von Formgedächtnislegierungen","date_updated":"2022-01-06T07:04:16Z","_id":"9570","language":[{"iso":"eng"}],"user_id":"55222","citation":{"mla":"Müller, Thomas, et al. “Verlässlichkeitorientierte Technologiebewertung Innovativer Aktortechnologien Am Beispiel von Formgedächtnislegierungen.” <i>2.

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.","lang":"eng"}],"issue":"3-4","publication":"Journal of Electroceramics","keyword":["Piezo ceramics","Bimorph","Tactile sensor","Tumour tissue"],"type":"journal_article","department":[{"_id":"151"}],"date_created":"2019-04-29T12:50:44Z","date_updated":"2022-01-06T07:04:16Z","intvolume":"        20","title":"Tactile tissue characterisation by piezoelectric systems","year":"2008","author":[{"full_name":"Stroop, Ralf","first_name":"Ralf","last_name":"Stroop"},{"first_name":"David Oliva","last_name":"Uribe","full_name":"Uribe, David Oliva"},{"last_name":"Martinez","first_name":"Melisa Orta","full_name":"Martinez, Melisa Orta"},{"full_name":"Brökelmann, Michael","first_name":"Michael","last_name":"Brökelmann"},{"full_name":"Hemsel, Tobias","first_name":"Tobias","last_name":"Hemsel","id":"210"},{"full_name":"Wallaschek, Jörg","last_name":"Wallaschek","first_name":"Jörg"}],"publication_identifier":{"issn":["1385-3449"]},"doi":"10.1007/s10832-007-9183-6","language":[{"iso":"eng"}]},{"publisher":"Springer US","_id":"9575","page":"209-214","volume":20,"user_id":"55222","status":"public","citation":{"ama":"Twiefel J, Potthast C, Mracek M, Hemsel T, Sattel T, Wallaschek J.

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.","lang":"eng"}]},{"date_updated":"2022-01-06T07:04:16Z","title":"Development of a biomedical tissue differentiation system using piezoelectric actuators","status":"public","year":"2008","author":[{"full_name":"Uribe, David Oliva","last_name":"Uribe","first_name":"David Oliva"},{"first_name":"Ralf","last_name":"Stroop","full_name":"Stroop, Ralf"},{"id":"210","full_name":"Hemsel, Tobias","last_name":"Hemsel","first_name":"Tobias"},{"last_name":"Wallaschek","first_name":"Jörg","full_name":"Wallaschek, Jörg"}],"publication_identifier":{"issn":["1075-6787"]},"doi":"10.1109/FREQ.2008.4622963","user_id":"55222","page":"91-94","language":[{"iso":"eng"}],"_id":"9576","abstract":[{"text":"In neurosurgery, delineation of tumor boundaries during resection of brain tumors is of substantial relevance.
