MOTOR (Italian PNRM)

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

Area: Smart Sensors

Detection of chemical/biological threats
Development of distributed sensors for homeland security application. The network makes use of two complementary techniques for sensing in the gas and in the liquid phase: hollow fiber based IRAS, and opto-chemical chip
Role of CREO
Development of the sensor for C sensing in the vapour phase.
Sensing solution / Technology developed by CREO (concept patented by Leonardo S.p.A.)
The sensing scheme patented by Leonardo SpA is based on Hollowf-Fiber Infrared Absorption Spectroscopy.
Source and detector are placed tens of meters apart, and coupled by an unrolled hollow fiber, that acts, at the same time, as an 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

TRL: 3
A breadboard with a fiber length of 2 meters tested succesfully with solvents and with CWA simulants with LoD in the 100s ppb and with a response time of few seconds from sampling to reporting.
