This paper discusses the electrical design of a seam monitoring device for felled seams. Felled seams are commonly found in commercial products, such as apparel garments, parachutes, tenting and geotextiles. The felled seam can be improperly formed during the seaming process, producing defects that may not be detected by visual inspection. The felled seam monitoring device ensures the detection of a faulty felled seam during the seam formation process. The design focuses on the utilization of inexpensive electronic technology and analysis of displacement-based sampling techniques to meet apparel manufacturer’s design specifications.
