| Outline of Final Research Achievements |
In this research, the thermal energy harvesting and piezoelectric response behavior for the lead-free piezoelectric composite materials were studied from both numerical simulation and experiment. Specifically, piezoelectric/Cu unimorph and piezoelectric nanoparticle dispersed polymer films were fabricated, and output voltage measurement due to temperature change and piezoelectric response evaluation were performed. Moreover, multi-physics numerical simulation was carried out and theoretical examination was added to the experimental result. Furthermore, the material and structure optimization of piezoelectric composites was discussed.
