Outline of Final Research Achievements

In order to provide meso-mechanical design criteria of novel eco-friendly smart electronic composite materials, we investigated the detection/response characteristics and power generation properties of barium titanate electronic composites 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. Based on the study on the detection/response characteristics and power generation properties of the electronic composites, optimal materials and structures were selected.
