Investigation of Geometric Effects on the SMARTweave Signal

Abstract

SMARTweave or Sensors Mounted As Roving Threads is an electrical grid comprised of orthogonal noncontacting conductive filaments used primarily to monitor the resin flow in the manufacturing of liquid-molded composite materials. It works on the principles of the half Wheatstone bridge and ionic mobility. It has been successfully demonstrated as a technology, but now the challenge is to characterize the system and its behaviors. The variables addressed in this report are basically geometric in nature. The following will each be investigated: the sensor materials and their perpendicular area of conduction, the separation from one node to the next in the horizontal plane, and the separation from one lead to the next in the vertical plane. Results are presented regarding the SMARTweave sensor materials and signals. The results on horizontal spacing, the area of conduction, and vertical separation will be presented.
