摘要

走與跑是最基本且最簡單的移動方式，但不當的行走與跑步姿勢，容易造成足部的受傷，更可能會導致相關部位的關節產生病變。近二十年來，隨著感測器技術之發展及處理器的普遍應用，各類型的足部壓力量測系統因應而生，而能即時的瞭解及長期監控步態狀況，以便隨時作步態調整及矯正，即時的透過醫師進行治療，以達護腳的功能，為重要之課題。
本研究提出一種護腳裝置及其方法，並以足部骨骼結構、生物力學及正確的走路步態，作為研發可抽取式足底壓力感測之護腳裝置及其方法的依據，且再以足底各區塊所測之壓力的之標準區域作為考量，並研究各種不正常步態狀況的判斷準則，以更符合足底實際量測步態的判斷，提供警示訊號給使用者，隨時作步態的調整，以達護腳的目的。本研究目前完成護腳系統之概念設計，並研製一種由高分子材料及奈米粉末、或奈米碳管所組成之感測器，作為護腳系統的核心感測元件，而感測元件經無數次配方改良及重覆性實際試驗，最後完成一種具有可承受無數次往復擠壓而未變形、高重覆性、壽命長且成本低廉特性的感測器，符合本護腳系統所需之述求，達到長期護腳的功能及效果。

Walking and running are the most basic and simplest movements. However, improper walking and running posture is apt to cause the injury of the foot and may further result in the pathological change of the relevant joints. In the past 20 years, with the development of the technology of sensor and the general applications of processor, all kinds of foot-pressure detecting systems have been developed. The most required and important topic, however, is to develop a system of being capable of immediate understanding and long-time monitoring user’s gait in order to, if necessary, adjust and correct the gait at any time, and to take necessary treatment under the doctor’s instruction simultaneously to fully achieve the function of protecting foot.
This study presents a foot-protecting device and method. It is based on the skeleton structure of foot, biomechanics and correct gait of walking to develop the collecting type of required foot-sole pressure-sensor. The foot-sole is divided into five regions. Each region’s average pressure is taken and compared with that of standard normal one. The criteria for all kinds of abnormal gaits have been proposed to provide more accurate judgment on the measured gait and warning message to the user as well. It could be, therefore, able to provide the function for the user to make any necessary adjustment at any instant to achieve the purpose of foot protecting.
This study has accomplished the conceptual design of the foot-protecting system, and has developed a sensor made by high polymer material, nano-powder or carbon nanotubes . This sensor is the core element of the system, and is obtained through hundred times of different prescriptions and tests. This sensor could endure over hundred-thousand times of reciprocating compress without deformation. It has the characteristics of high repeatability, long life and cheap. This sensor has been confirmed in satisfying the requirements for the foot-protecting system to accomplish the function of long-term foot-protecting.
