本研究利用 K2Ti4O9 奈米線作為反應前驅物，而後再將 K2Ti4O9 奈米線與BaCO3粉末在共晶鹽 KCl-NaCl 中以熔鹽合成法透過離子置換過程成功製備出 BaTiO3 奈米線，其反應是利用self-sacrificing template effect 及 Kirkendall effect，所合成的產物形貌與前驅物 K2Ti4O9 奈米線相近，而後將 BaTiO3 奈米線放置於高溫爐內於退火 2 小時使得表面平坦化及奈米線反應更完全，並且晶粒排列成長成單晶結構。
本研究以壓電力顯維鏡來量測 BaTiO3 奈米線的壓電性質，壓電量測分別以 VPFM 及 LPFM 兩種模式量測，其中以 VPFM 模式量測下壓電係數 d33 經計算約為 0.89 pm/V，而以 LPFM 模式量測下測得的壓電係數 d15 為 51.9 pm/V，以 LPFM 模式所偵測到的壓電係數相當優良，證明 BaTiO3奈米線有良好的壓電特性。本研究利用 BaTiO3 奈米線與 PDMS 高分子混合成功製備出奈米發電機作為應用，並添加奈米碳管幫助分散奈米線分散，當添加12 wt % BaTiO3 奈米線及1 wt % 奈米碳管時奈米發電機可得到最高的輸出電壓及輸出電流，約為 1.8 V及125 nA，而在極化處理過後奈米發電機的輸出電壓及輸出電流更可達到 3.4 V及300 nA，由此可證明由 BaTiO3 奈米線所製作而成的奈米發電機具有絕佳的發電能力。
