The invention relates to resistance-type stretchable multi-axis force sensing yarn. The resistance-type stretchable multi-axis force sensing yarn comprises a piece of core yarn and two pieces of fasciated yarn, a yarn body is formed by winding one piece of fasciated yarn on the core yarn in a helical mode, and wrap yarn is formed by winding the other piece of fasciated yarn on the yarn body in a helical mode in the opposite helical direction of the previous piece of fasciated yarn; the wrap yarn is of a negative poisson's ratio yarn structure, and subjected to conductive treatment. The requirements that the yarn is seamlessly embedded into traditional clothing to achieve interference-free real-time monitoring of human body functional motions and activities can be met. 本发明涉及种电阻式可拉伸多维力传感纱线，包括根芯纱和两根包缠纱，根包缠纱通过螺旋的方式缠绕在所述芯纱上形成纱线，另根包缠纱以和前根包缠纱相反的方向螺旋缠绕在所述纱线上形成包覆纱；所述包覆纱为负泊松比纱线结构，且进行导电处理。本发明能够满足无缝嵌入传统服装中实现人体功能性运动及活动的无干扰实时监测要求。
