Paragraph starter
Research indicates that the performance of conductive inks on textile substrates is significantly influenced by the fabric's inherent properties, such as absorbency and surface texture. Studies have shown that while adhesion can be good, conductivity may be reduced compared to application on non-porous materials. Therefore, careful selection of fabric type, optimization of ink viscosity for deposition thickness, and refinement of application techniques are critical for achieving desired electrical functionality in smart textile design.
