下面将通过具体实施例来对本发明进行具体说明。
实施例1
首先，将质量百分含量为30％的导电填料与TPU(弹性体)均匀混合，并将混合均匀后的所述导电填料与弹性体置于具有图形的治具中预先成膜，得到一弹性导电层11，再在低温90～130℃，2MPa～8Mpa的压力的条件下，将所述弹性导电层11与所述织物层12压合8～35秒，使得所述弹性导电层11与所述织物层12连结在一起，得到一弹性导电复合织物100。其中，所述弹性导电复合织物100的电阻值介于100Ω～103Ω之间。之后，施与一张力于所述弹性导电复合织物100，所述弹性导电复合织物100在所述张力作用下伸展。最后，测量不同张力下的所述弹性导电复合织物100的电阻值与所述弹性导电复合织物100的长度应变增量。
其中，在实施例1中，所述弹性导电复合织物100的长度应变增量为ε，则所述弹性导电复合织物100的电阻值RT与应变增量ε关系为：RT＝10.35e0.33ε，此处ε可为整数或小数。
实施例2
首先，将质量百分含量为60％的导电填料与TPU及SEBS(弹性体)均匀混合，并将混合均匀后的所述导电填料与弹性体直接涂布在所述织物层12上，再以110℃热风烘干20分钟，得到一弹性导电层11及一弹性导电复合织物100。其中，所述弹性导电复合织物100的电阻值介于10-1Ω～102Ω之间。之后，施与一张力于所述弹性导电复合织物100，所述弹性导电复合织物100在所述张力作用下伸展。最后，测量不同张力下的所述弹性导电复合织物100的电阻值与所述弹性导电复合织物100的长度应变增量。
其中，在实施例2中，所述弹性导电复合织物100的长度应变增量为ε，则所述弹性导电复合织物100的电阻值RT与应变增量ε关系为：RT＝0.75+1.68εε，此处ε可为整数或小数。
本发明还提供一种应用所述弹性导电复合织物100以侦测并显示所述弹性导电复合织物的电阻值及电阻值变化的电子产品200。
由上可知，所述弹性导电复合织物100的弹性应变增量与其电阻变化相对应并存在指数或线性关系，因此，通过侦测所述弹性导电复合织物的电阻值变化，可以得到所述弹性导电复合织物100的应变增量，根据所述应变增量的变化能够解析肢体屈曲和伸展运动的变化。
另外，所述弹性导电复合织物100的织物层12与人体绝缘，且所述弹性导电层11并未与人体直接接触，因此，人体并不会影响所述弹性导电复合织物100的电阻值。
再者，所述弹性导电复合织物100还具有透气、亲肤及舒适柔软的性能。
以上所述，仅是本发明的较佳实施方式而已，并非对本发明任何形式上的限制，虽然本发明已是较佳实施方式揭露如上，并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施方式，但凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施方式所做的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
