A sensor yarn (10) having a thread core (11) around which first and second conductors (12, 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 one embodiment, the sensor yarn (10a) has a capacitance (Cl) per unit of length that 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 or second conductors (12, 13) or by a change of the relative permittivity (E) of the sensor yarn (10). In another embodiment, the sensor yarn (10b) has photosensitive material (30) and a length change is effected by an incident to the 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) changes, which can be determined by means of an evaluating unit (17).

There is provided a textile including a strain sensing portion integrally knitted therein and including groups of courses of yarn, each group including a first course of conductive yarn, a second course of dielectric yarn, and a third course of conductive yarn, each course including a plurality of knitted loops. The second course is arranged in between the first and third courses and configured to have a higher elasticity than the first and third courses such that when the strain sensing portion is at a relaxed state, corresponding knitted loops of the first and third courses are caused by a corresponding knitted loop of the second course to contact each other, and when the strain sensing portion is at a stretched state, corresponding knitted loops of the first and third courses are caused by a corresponding knitted loop of the second course to be not in contact with each other.

A fabric-based item may include fabric formed from intertwined strands of material. The strands of material may include extruded strands. Strand extrusion equipment may have electrically adjustable sources such as one or more sources of different polymers, dyes, particles, wire, and other elements to be incorporated into an extruded strand. The properties of the strands such as strand stiffness, strand diameter, conductivity, magnetic permeability, opacity, color, thermal conductivity, sand strength, may be varied along their lengths. Fabric formed from the strands may have different areas with different properties. Markers may be formed from particles at particular locations along the lengths of the strands, may be optical marker structures formed from circumferential rings of ink or other visible material on the strands, or may be other markers that can be sensed using electrical sensing, magnetic sensing, optical sensing, or other types of sensing when forming fabric from the strands.

A tension adjusting and stabilization system and method can include an elastic compression bandage including long-stretch elastomeric yarns and an approximate 1:1 stretch characteristic. A change in length-wise stretch of the bandage results in an approximately proportional change in compressive pressure provided by the bandage. The system and method can further include a means for indicating a qualitative degree of tension of the bandage and a means for indicating a quantitative amount of pressure being applied by that degree of tension.

An example wearable device that includes a conductive deformable fabric is described herein. The conductive deformable fabric has a conductive trace that has a non-extendable fixed length along a first axis, and the conductive trace is sewn into a fabric structure to produce a conductive deformable material. The fabric structure includes a stitch pattern that facilitates the conductive trace to unfold and fold in an oscillating fashion to allow the conductive trace to expand and contract, respectively, along the first axis without exceeding the fixed length of the conductive trace. The conductive deformable material is positioned within the wearable device such that when the wearable device is worn, the stitch pattern is over a joint of the user to allow the stitch pattern to expand or contract along with the movement of the joint.
