本論文的主要目的是開發「足底壓剪力量測之技術」,相關的研究主題分為二部分研究。第一部分研究主題是建立「微結構複寫式足底壓剪力量測墊」,此量測墊是由彈性pu以及poly硬質不飽和聚酯樹脂所合成,並設計不同之微結構造型來做比較,期望可以與無碳複寫紙之試片在鞋內量測出足底壓力與剪力變化圖,並藉由所製造出的微結構複寫式足底壓剪力量測墊,取得行走以及運動時所留下之壓力與剪力行為,分析其最佳使用狀況以及行為判讀;第二部份的研究主題是「微結構影像式壓剪力量測法」,利用本實驗室先前所開發之足壓量測平台,擷取出足底壓力資料,將各別圖片作影像處理後,以足壓影像特徵面積的Pixel來做數值運算處理後,來分析出步行時足底壓力與剪力之關係,並推導出剪力行為,整合以上兩部分,以建立一創新可滿足裸足與鞋內量測足底壓剪力之技術。 藉由本研究計畫的實施,已成功建立「足底壓剪力量測之技術」的能力,設計出可放置於鞋內之足底壓剪力量測片,可以直接由無碳複寫紙觀察鞋內壓剪力變化情形,最後進行足底壓力量測及足底剪力分析,達到足底壓剪力量測的目的,對於現有之足壓量測技術實為一大突破。
This study is to develop the plantar pressure and shear force measuring technologies. There are two parts of this study. The first part is the planter pressure and shear force recording plate based on micro structure imprint. The second part is the image based planter pressure measuring and shear force calculation. For the recording plate, it is fabricated by hard poly and soft PU. There are many different geometric designs have been tested. For the image based measuring system, a way to calculate the shear force based on the normal pressure distribution has been proposed. By the combination of the above two measuring method, the plantar pressure and the shear force of the bear feet and wear shoes can be measured. Different from conventional foot pressure technologies, the new system brings a new foresight in foot diagnostic by bring the foot pressure together with shear force measuring.
