Technology Description:

This invention describes a one-of-a kind smart textile fabric, a synthetic knit that is a soft stretchy material. It responds to stretching with a change in electrical resistance and thus provides a simple mechanism to measure displacement. This cutting edge technology is an excellent alternative to the rigid, bulky and uncomfortable sensors commercially available today.


  • Novel substrate and thread type
  • 10x greater resistance than existing stretch sensor 
  • Flexible stitch geometry – multiple orientations 
  • High accuracy and precision sensor 
  • Overcomes the challenge of bulky wearable sensing 


  • Athletic apparel
  • Wearable technology 
  • Health monitoring devices
