    Abstract: The invention relates to a sensor yarn (10) having a thread core (11), around which a first conductor (12) and a second conductor (13) are helically wound. The two conductors (12, 13) are electrically insulated from each other and from the thread core (11). The two conductors (12, 13) form a capacitive component (15) together with the thread core (11). In the case of a first sensor yarn (10a), the capacitance (Cl) per unit of length changes in the direction of extent (E) of the sensor yarn. This can be accomplished by a change in the winding geometry of the first conductor (12) or of the second conductor (13) or by a change of the relative permittivity (ε) of the sensor yarn (10). A second sensor yarn (10b) has photosensitive material (30), and therefore a length change can be caused by incident light (L). As a result of a length change or other deformation of the sensor yarn (10a, 10b), the total capacitance (CG) of the sensor yarn (10a, 10b) in question changes, which can be determined by means of an evaluating unit (17).

    Abstract translation: 本发明涉及一种具有螺纹芯(11)的传感器纱(10),第一导体(12)和第二导体(13)围绕该螺纹芯被螺旋缠绕。 两个导体(12,13)彼此电绝缘并且与螺纹芯(11)电绝缘。 两个导体(12,13)与螺纹芯(11)一起形成电容组件(15)。 在第一传感器纱线(10a)的情况下,每单位长度的电容(C1)沿着传感器纱线的范围(E)的方向变化。 这可以通过改变第一导体(12)或第二导体(13)的绕组几何形状或通过改变传感器纱线(10)的相对介电常数(ε)来实现。 第二传感器纱线(10b)具有感光材料(30),因此入射光(L)可引起长度变化。 由于传感器纱线(10a,10b)的长度变化或其他变形,所涉及的传感器纱线(10a,10b)的总电容(CG)改变,这可以通过评估单元 17)。
