A stretchable carbon composite is integrated by stencil printing onto two different types of textile, with different yarn morphologies. The impact of the knit structure and coating direction on the performance of the sensor composite is evaluated and used to derive a model estimating nominal resistance at a given strain near the percolation threshold ...
