To estimate this amount a priori manufacturing of prototypes a mathematical model is very helpful. Within this contribution we will introduce a model based on electro-mechanical circuit theory. Its parameters are identified by measurements and the model is validated by comparison to experimental results. The model is designed to support the development-engineer in the dimensioning of energy harvesting units to specific application demands. Two main challenges in device design are investigated with the mathematical model: influence of the ambient excitation frequency, and influence of the load impedance. Typically, the equivalent model approach delivers models for piezoelectric elements that are driven in resonance by electrical excitation. In the case of energy harvesting the piezoelectric elements are excited mechanically and most often non-resonant. Thus, we first set up a mechanical equivalent model for base excited systems. In first approximation it represents an energy harvesting unit around one resonance frequency. The model is expandable for a wider frequency range using the superpositioning of multiple circuits. From the viewpoint of optimum energy transformation between mechanical and electrical energy it is favorable to drive piezoelectric elements at resonance or anti-resonance. Thus, an energy harvesting system should be tuned to the excitation frequency.}}, editor = {{Twiefel, Jens and Richter, Björn and Hemsel, Tobias and Wallaschek, Jörg}}, pages = {{616909--616909--10}}, title = {{{Model-based design of piezoelectric energy harvesting systems}}}, doi = {{10.1117/12.658623}}, volume = {{6169}}, year = {{2006}}, } @inproceedings{9558, author = {{Wilmanns, S and Nakamura, K and Mracek, Maik and Hemsel, Tobias}}, booktitle = {{Proceedings of 2nd International Workshop on Piezoelectric Materials and Applications in Actuators}}, pages = {{205}}, title = {{{Non-resonant piezoelectric motors driven in audible frequency range}}}, volume = {{Band 180}}, year = {{2006}}, } @inproceedings{9559, author = {{Zhou, W and Fu, Bo and Hemsel, Tobias and Wallaschek, Jörg}}, booktitle = {{Proceedings of 2nd International Workshop on Piezoelectric Materials and Applications in Actuators}}, pages = {{213}}, title = {{{Piezoelectrics in dental tools}}}, volume = {{Band 180}}, year = {{2006}}, } @inproceedings{42429, author = {{Fuchs, Christian and Horiuchi, Yoshihide and Kordes, Urban and Rivera, Barbara and Rowland, Gordon and Walton, Doug}}, booktitle = {{Proceedings of the Thirteenth Fuschl Conversation}}, editor = {{Metcalf, Gary and Chroust, Gerhard}}, isbn = {{3-902457-13-9}}, pages = {{12--23}}, publisher = {{Institute for Systems Engineering and Automation, Johannes Kepler University Linz}}, title = {{{Fuschl Extension: Igniting a New Form of Conversation}}}, year = {{2006}}, } @article{26278, author = {{Ziegler, Martin and Fuchssteiner, Benno}}, issn = {{0020-7748}}, journal = {{International Journal of Theoretical Physics}}, pages = {{693--717}}, title = {{{Nonlinear Reformulation of Heisenberg's Dynamics}}}, doi = {{10.1007/s10773-005-7048-9}}, year = {{2005}}, } @article{21219, author = {{Meschut, Gerson}}, issn = {{ISSN 0947-9333}}, journal = {{Konstruktion}}, pages = {{92--93}}, title = {{{Mischbauweise sorgt für frischen Wind}}}, volume = {{04}}, year = {{2005}}, } @misc{21229, author = {{Meschut, Gerson and Küting, Jens}}, title = {{{Verfahren und Vorrichtung zur Direktverschraubung}}}, year = {{2005}}, } @misc{21230, author = {{Freitag, Volker and Hahn, Ortwin and Meschut, Gerson and Ruther, Michael and Timmermann, Rüdiger and Wiese, Thomas}}, title = {{{Fügeverfahren zum Verbinden von überlappend angeordneten Fügeteilen und entsprechende Fügevorrichtung}}}, year = {{2005}}, } @inbook{19142, author = {{Seng, Eva- Maria}}, booktitle = {{Kirchen, Märkte und Tavernen.
