Wearable Ionizing Radiation Detector for General Populations


Project TitleWearable Ionizing Radiation Detector for General Populations
Track Code5510
Short Description

Conducting fibers are produced and integrated into devices to provide the first real-time, portable, wearable and inexpensive signaling of radiation exposure at threshold levels relevant for warning of danger to humans.


The fibers are made by electrospinning solutions of a fiber-forming polymer and a conducting polymer (PEDOT:PSS). They can be integrated into circuits by spinning across electrodes patterned on chips, or incorporating as yarns in place of wires on 'breadboard' circuits. Conductivity of the fibers decreases with exposure to ionizing radiation, and the change in conductivity triggers a signal such as a light, sound or vibration indicating radiation exposure.


Potential Applications

  • Personal radiation detector can be integrated into clothing, jewelry, or personal electronic devices to monitor radiation for hospitals, doctor's offices, laboratories, nuclear power plants, homeland security, etc.



  • Real-time measurement and warning
  • Portable
  • Low cost
  • Can tie into sensing networks
