Dust

Dust was an espionage tool that was developed by GAR Procurement Development during the Clone Wars. Composed of microscopic dust-like transmitters, in appearance it looked like powdered permaglass. It was used to track targets or could be scattered on the battlefield for invisible monitoring.

There was an individual tracking mechanism included in each batch, which was used to tag targets. Dust was most effective when directed at the mouth or face of a target so that it was inhaled. It was slightly sticky, enabling it to attach itself to the victim; and could actively transmit for four to five weeks.

With the aid of an optical EM filter, which detects electromagnetic emissions, Dust could be visually distinguished, casting a pinkish brown tinge on the image.
