57% of terrorists’ attacks in the world are conducted with explosives, a serious threat especially in Airports, since they are easy to acquire but difficult to spot. Eye On Air developed I-Must (Ion Mobility Universal Sensor Technology), an ultra-sensitive and compact for Ion Mobility Spectrometry able to detect Volatile Organic Compounds. Its exceptional sensitivity (0.1 ppb) and specificity (150+ dangerous compounds detectable), and an extremely low time of analysis (2-5 s), make this enabling technology the perfect fit for Explosive Trace Detection (ETD) in Airports. Its ultra-small dimensions (comparable to a 1 € coin) makes I-Must a real game changer: possibility arises to implement distributed security systems for explosive detection. Its integration in a mat-like device, the so-called AirBrush, makes the device suitable for shoes’ scanning without the need, for passengers, to remove shoes. This is a great achievement for airports, who need to perform effective security controls, usually time consuming, while granting a pleasant user experience for their customers, passengers that usually need to wait long time for security checks. The goals of Phase 2 are to engineer the scaled-up version of the AirBrush and to conduct operational tests in one of the most important European Airports (already secured). The device will need to be validated by the competent authorities and will be then ready for commercialization.
