Abstract (en)
[origin: WO2015144597A2] 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 (de)
Die Erfindung betrifft ein Sensorgarn (10b) mit einem Fadenkern (11), um das schraubenförmig ein erster Leiter (12) sowie ein zweiter Leiter (13) gewickelt sind. Die beiden Leiter (12, 13) sind gegeneinander und gegenüber dem Fadenkern (11) elektrisch isoliert. Die beiden Leiter (12, 13) bilden mit dem Fadenkern (11) ein kapazitives Bauelement (15). Das Sensorgarn (10b) weist photosensitives Material (30) auf, so dass durch einfallendes Licht (L) eine Längenänderung bewirkt werden kann. Eine Längenänderung bzw. eine andere Verformung des Sensorgarns (10b) führt dazu, dass sich die Gesamtkapazität (CG) des Sensorgarns (10b) ändert, was durch eine Auswerteeinheit (17) ermittelt werden kann.
