A key advantage of E-yarns over other electronic textiles is that they are completely undetectable to a wearer allowing for electronics to be comfortably placed near the skin. Textiles made using E-yarns maintain all of their normal textile characteristics such as drape, flexibility, and heat and moisture transfer characteristics.

E-yarns have been created with many different functions, examples include:

  • LED E-yarns for fashion and performance applications. LED E-yarns can also be used as component in a textile heart rate sensor.
  • Temperature Sensing E-yarns for health monitoring and sports applications. Temperature can an important indicator of illness or can show a change in performance in sports.
  • Acoustic Sensing E-yarns for health monitoring. Overexposure to noise can cause hearing damage. The acoustic sensing E-yarn can act as a microphone to record sound, ensuring that the wearer is only exposed to safe levels.
  • Vibration Sensing E-yarns for health monitoring. Overexposure to vibration can cause damage to the body. Recording and logging the vibration that the wearer is exposed to can ensure that overexposure does not occur.
  • Light sensing E-yarns. Light sensing E-yarns can be used in combination with LED E-yarn to create sensing systems able to monitor heart rate.
  • Solar E-yarns for energy harvesting. Electronic textile devices require power which can be provided by a solar E-yarn.
  • Supercapacitor E-yarns to store energy. Supercapacitors can be used to store electrical energy to be used later. Solar E-yarns and supercapacitor E-yarns can be used together to power electronic textiles.
