New Sensor Technology Development and Integration for End of Service Life Indicators - FY09

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.

Current Information can be found at: New Sensor Technology Development and Integration for End of Service Life Indicators - FY10


  • This project will develop sensor systems for integration into personal protective equipment (PPE). These sensor systems will provide information regarding PPE performance and end-of-service life.

Applicable Standards

  • OSHA standard 1910.134(d)(3)(iii)(B)(2)
  • 42 CFR Part 84 Subpart G, Section 84.1157. Vol 60, Number 110

Key Partners

  • Carnegie Mellon University, Research partner
  • U. S. Air Force AFOSR, Funding partner



  • General industry workers and emergency responders

Project Scope

  • Development of partnerships with technology providers and manufacturers
  • Test prototype chemical sensors systems
  • Construct cartridge simulator test bed
  • Collaborate with manufacturers to test sensor package integrated into respirator cartridges


  • Q1 Migrate new electronics to sensor testing
  • Q2 Submit paper covering findings from sensor integration and cartridge simulator work to OD for approval
  • Q3 Characterize first-generation integrated MEMS capacitive humidity sensor using a specific polymer (e.g. polyimide) for water vapor uptake
  • Q4 Evaluation of data on chemiresistors made from nanoparticle materials for long-term behavior, over months


  • Manuscripts published or submitted to peer review journals (approx. 3)
  • Presentations at conferences (approx. 7)
  • Standards committee meetings & public meetings (approx. 24)


  • Respirators with ELSI/RSLI capabilities are the first likely commercial products to result from this work.

    • Implementation of these devices in respirators could result in modification of certification standards.
