Consequently, those effects, i.e. the system’s dynamic behavior, need to be known. For the piezo-composite transducers in an ultrasonic transmission line, a model based approach is used to describe their dynamic behavior and take into account its dependence on the environment temperature and the acoustic impedance of the target medium. Temperature-dependent model parameters are presented, which are obtained by performing a multiplepart identification process on the transducer model, based on electrical impedance measurements [1]. The identification process uses an inverse approach for optimizing a subset of the model parameters. Additionally, algorithmic differentiation methods are used to determine accurate derivatives. In a final optimization step, impedance measurements taken at different temperatures are used to determine the temperature dependencies of the model parameters. These can then be used to assess the plausibility of the identification results. Additionally, the parameters can be expressed as polynomials in the temperature to take different operating conditions into account.","lang":"eng"}],"type":"conference","publication":"AMA Conferences 2015"},{"_id":"9574","user_id":"55222","department":[{"_id":"151"}],"type":"journal_article","status":"public","date_updated":"2022-01-06T07:04:16Z","author":[{"full_name":"Stroop, Ralf","last_name":"Stroop","first_name":"Ralf"},{"full_name":"Uribe, David Oliva","last_name":"Uribe","first_name":"David Oliva"},{"first_name":"Melisa Orta","last_name":"Martinez","full_name":"Martinez, Melisa Orta"},{"first_name":"Michael","full_name":"Brökelmann, Michael","last_name":"Brökelmann"},{"first_name":"Tobias","last_name":"Hemsel","id":"210","full_name":"Hemsel, Tobias"},{"full_name":"Wallaschek, Jörg","last_name":"Wallaschek","first_name":"Jörg"}],"volume":20,"doi":"10.1007/s10832-007-9183-6","publication_identifier":{"issn":["1385-3449"]},"citation":{"ama":"Stroop R, Uribe DO, Martinez MO, Brökelmann M, Hemsel T, Wallaschek J.

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"}],"publisher":"Springer US","date_created":"2019-04-29T12:50:44Z","title":"Tactile tissue characterisation by piezoelectric systems","quality_controlled":"1","issue":"3-4","year":"2008"}]
