As an alternative to impinging steady flow jets used in detectors of illegal substance traces on clothings of people who recently came into contact with explosives or drugs, authors investigated synthetic jets with zero time-mean nozzle flow rate. 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
