Measuring garment pressure at any point using a wearable sensor

Abstract

In this article, we build an oval mechanical model at any circumference of seamless weft, founded upon the analysis of body shape in order to analyze the curvature radius at arbitrary circumference and part. Clothing pressure is built according to the Laplace equation. Depending on the elastic fabric tensile deformation, clothing pressure at any circumference was subsequently analyzed. The results demonstrate that clothing pressure increases in areas of largest body curvature, which is highest on both sides but is smallest on the body front center and back center. In addition, weft flexible fabric sensors, which are knitted silver-plated yarn into seamless underwear as pressure sensors, are designed to test the relationship between sensor’s resistance and the clothing commodious quantity in order to explore the relationship between resistance change and clothing pressure. The results show that as the size of those wearing a given garment changes, the resistance of the flexible sensor in the clothing will also change. Specifically, weight and size are associated with greater clothing pressure and higher resistance of the flexible sensor. Because clothing pressure and flexible sensor resistance are linked to the tensile tension of clothing, we have been able to determine the relationship between clothing pressure and flexible sensor resistance. This achievement is expected to provide the basis for further studies assessing the comforting pressure of seamless underwear and ease of wear.
