This invention relates to a leg-protection system that is replaceable, highly mobile, and can continuously examine the foot pressure and shear force. The main unit includes: gasket, the array-type force sensors for measuring normal and shear stress, signal amplified circuit, A/D converters, microprocessor, soft circuit-board, wireless transmitting device, computer or cell-phone and the software for post signal-processing etc. The user can put this device in the shoes to become a part of the original shoe-pad as a sole pressure-measuring device during running and walking. The measured sole-pressure area is divided into several blocks in accordance with the bone structure of foot and the ratio of bearable normal to shear pressure. Each block can examine the normal and shear force independently and, then, transmit the data by a wireless or a portable network device to the computer or the cell-phone. The data can be used to set up the average value and standard range of users sole pressure and average shear pressure for each block. Thereafter, the user’s running and walking average sole pressure and shear pressure could be, then, compared with those of user’s own average value and standard range to judge any abnormal condition of the sole. As a result of that, the device can immediately figure out the user’s gait situation and provide warnings or suggestions at once to achieve the function and purpose of foot-protection.一種可抽換及機動性高且可不斷量測足底壓力及剪力之護腳系統,其主要包括有:軟墊、陣列式壓力與剪力感測器、訊號放大電路、微處理器、類比/數位訊號轉換器、軟性電路板、無線傳輸器、電腦或手機及足底壓力及剪力檢測軟體等。其方法為:使用者可將本裝置置放於鞋內,成為原鞋墊的一部份,在進行跑步與行走時,作為足底壓力及剪力感測的量測體。依足部骨骼之結構及可承受壓力與剪力的比值不同而分成若干區塊,各自獨立測取各區塊的壓力與剪力之分佈值,並經無線傳輸或近身網路,傳送至電腦或手機,建立使用者足底承受壓力及剪力各區塊的平均值。其後則根據使用者跑步與行走的狀況,將所量得之足部壓力及剪力的平均值與標準範圍值作比對,此裝置將立即判斷出足底正常與異常之狀況,提供使用者瞭解其即時步態情形,並適時提出警告或建議,達到護腳的功能與效果。501‧‧‧腳跟內側(感測區塊)502‧‧‧腳跟外側(感測區塊)503‧‧‧腳掌內側(感測區塊)504‧‧‧腳掌中央(感測區塊)505‧‧‧腳掌外側(感測區塊)
