摘要

本研究研製一高分子材料及奈米粉末所合成之奈米複合材料，作為可撓式壓力量測感測器。其高分子材料為可流動之膠狀型態及優良柔軟性質，且凝固後具有承受高荷重擠壓而未損壞之特性，其流動之特性可減少於印刷製作過程中之困難度，因此，本研究選用PDMS高分子材料作為感測材料之基材。本研究根據高分子材料與奈米粉末的不同特性，依不同比例摻入進行試驗分析，尋求出最符合壓力感測器之用的複合材料，並研製具有可印刷特性之奈米複合材料最佳製程及電容感測電路，使其可適用於軟性且可撓之陣列式壓力感測系統，並完成測試加以證實其可行性。

This study has developed a Nano Composite Materials, made by high polymer material and nano powder materials, which can be used for flexible measure sensor. The high polymer material has the characteristics of soft and flowing ability in colloidal patterns. Moreover, this high polymer material should have the capacity of high load without damage after solidified. The characteristics of flowing ability of the high polymer material can reduce the possible difficulty in the printing process. Therefore, the PDMS high polymer material is used as the substrate materials of sensor. We mix the high polymer material with nano powder in different proportions according to their different characteristics to perform the experimental study. This study has found the suitable composite material for the substrate of pressure sensor. We have also developed the best fabricated process for this printable composite materials and the printing process which can be used in the fabrication of array-type flexible sensor system. Its feasibility has been confirmed through fabricating a prototype.
