<P>PROBLEM TO BE SOLVED: To provide a sole slippage measuring device capable of measuring slippage of a sole in the inside of each of pair of shoes during walking. <P>SOLUTION: The device includes a sensor section 2 to be fixed in a footwear 10 (or insole), and a measuring device 3 connected to the sensor section 2 to measure variation in an electrical resistivity of the sensor section 2. The sensor section 2 is made of a pile fabric 20 having a plurality of piles 22 formed upright on a base cloth 21, and the pile fabric 20 is formed by weaving a covering yarn 4 formed by rolling winding yarns 41, 42 having conductivity around a core yarn 40 made of an elastic yarn. The winding yarns 41, 42 comprises a voltage-sensitive conductive yarn in which an electrical resistivity changes depending on expansion/shrinkage by blending a conductive fiber and a non-conductive fiber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
