MOTOR - Development of distributed sensors for monitoring and detection of chemical/biological threats

MOTOR

Project  acronym: MOTOR

Project full title: ”Development of distributed  sensors for  monitoring and detection  of chemical/biological threats“

Funding: The project is financially supported by the Italian  Ministry of Defense through the PNRM

Topic: detection of  chemical/biological threats

Goal: Development of distributed sensors for homeland security application. The network makes use of two complementary sensing techniques:  hollow fiber based IRAS, and opto-chemical chip

Concept/Technology (Patented by FINMECCANICA)

•Sensing based on Hollow-Fiber InfraRed Absorption Spectroscopy (HF-IRAS)

•Source and detector are placed tens of meters apart, and coupled by an unrolled hollow fiber, that acts, at the same time, as on optical coupler and a gas cell. Air is sampled and circulated inside the fiber by a mini-pump, through micro-holes equally spaced along the fiber.

•The fiber can be spread to ground, cabled to walls, or unrolled inside air ducts. The sensor fits very well indoor scenarios with strong spatial constraints

Requirements CREO sensor

  • Distributed architecture(line-sensor)
  • Response time of seconds
  • Sensitive to nerve agents
  • Low false alarm rate
  • Limit of Detection in the hundreds ppbs

Role of CREO: development of the hollow fiber based IRAS sensors

Perspectives: similar system architecture could be used to detect and identify drugs, TICs or IEDs’ precursors
