本文所讨论的是：通过在橡胶管内注射水性碳管浆材料而制成可拉伸弹性导线在弯曲和平直拉伸两种情况下，导线的电阻与弯曲角度和拉伸长度之间的关系.实验发现导线在平直拉伸的情况下，其电阻的变化与其拉伸长度有非常好的线性关系，在弯曲的情况下也有一定的函数关系.本文尝试用导电通道理论和量子隧穿效应来解释这两种规律背后的原因.在得到导线弯曲和拉伸的程度与其电阻之间的关系后，在实际应用中就可以通过测量导线的电阻来得到导线的变化情况，可以应用于机器人行业、柔性电子设备、可穿戴电子设备等方面，具有广泛的应用前景.

This paper discusses the relationship between the resistance of stretchable elastic wires, made by injecting water-based carbon nanotube slurry into rubber tubes, and the bending angle and stretching length of the wires under two conditions: bending and straight stretching. Experimental results show that, under straight stretching, the change in resistance has a strong linear correlation with the stretching length. Under bending, a functional relationship is also observed. This paper attempts to explain these patterns using conductive channel theory and quantum tunneling effect. After establishing the relationship between the degree of bending and stretching of the wire and its resistance, the wires changes can be measured by its resistance in practical applications. This offers broad potential for applications in robotics, flexible electronics, wearable devices, and more.
