The actuator designed to generate the synthetic jet has an unusual annular nozzle, creating between the nozzle exit and the cloth surface a space separated from the surrounding atmosphere. The detected traces are carried through this space to the detector inlet. The problem encountered, because of the variability of the examined persons, is the need to reach to very large distances.
