| Outline of Final Research Achievements |
In order to provide meso-mechanical design criteria and development technique of novel eco-friendly smart devices, we investigated the detection/response characteristics and fracture/fatigue behavior of piezoelectric material and thin-film systems from both a theoretical and experimental point of view using multi-physics approach. Electromechanical interactions, micro- and nano-structures, chemical composition, additive element, and fabrication time/temperature were considered. As a result, a study on the meso-strength and function evaluations of the smart piezoelectric material and thin-film systems was established.
