The document discusses the significance of electrical interconnections in smart textiles, highlighting their role in wearable device functionality and overall performance. It outlines various integration methods, including sewing flexible cables, weaving with conductive yarns, and embroidering conductive threads. Key factors for effective interconnections include comfort, reliability, and resistance to wear and washing.

3. Importance of Electrical
Interconnections in Textiles
 Electrical interconnections are crucial for the
functionality of wearable components.
 Efficiency of cabling affects the overall
performance of smart textiles.
 Key factors include comfort, reliability, resistance
to repetitive stresses, washing, and daily
activities.

4. Integration Methods
•Flexible cables are sewn into garments to connect sensors
• and electronic devices.
•Examples of conductive textile buses and elastic ribbons

5. Fabric-Level Electrical Interconnections
 Conductive yarns can be either partially fixed on the fabric's surface or
embedded within the fabric structure.
Weaving/Knitting with Conductive Yarns
 Conductive yarns replace non-conductive fibers during the textile
manufacturing process at specific locations
 Example: Integrated interconnection using two elastic conductive yarns
made by twisting stainless steel yarn around an elastic core (Lycra) and
covering it with polyester yarn.

6. Embroidering Conductive Thread
 Conductive threads are embroidered onto finished fabrics
at a later manufacturing stage.
 Example:
 Textile antenna: Conductive yarn (insulated or not) is
fixed on the fabric using standard yarn embroidery
