As a result, scientists at Fraunhofer FEP incor-porated a bimorph cantilever beam that constitutes thin coatings made of aluminum scandium nitride which could be used to monitor the logistics of freight train containers. Designing, analyzing, and optimizing the models is the main goal (using COMSOL 6.0). Initially, a comparable model was simulated using COMSOL 6.0 to confirm the experimental and simulation results. Then, the prototype model is topo-logically optimized with the static deformation structural finite element anal-ysis using the multi-physics simulation software COMSOL 6.0, to achieve a uniform stress distribution for the model, which was the exploratory require-ment to get the better performance of the model in which several optimized designs were analysed. All of the improved modifications of the existing designs were examined with regard to the results of the time-dependent analysis, they were all determined to help the model be enhanced by giving the impression that higher voltage output for the application was possible. The generated model was deemed trustworthy since it agreed with the earlier investigations. More investiga-tions and experimental validations of those optimized models, however, are required to fully elucidate the mechanism of structure and development of these optimized models.enDDC::600 Technik, Medizin, angewandte Wissenschaftenmaster thesis
