A European research group has an answer for catching people who aim to make explosive devices at home. Waste products that go down the drain deliver clues. Sensors that can identify these ingredients and sound an alarm are the solution, Bomb-making residue in city sewers may be an important signal for finding bomb-makers out, thanks to special sensors placed in sewers. A project called EMPHASIS aims to do just that. Emphasis is an EU-funded project of team members who are working on a method of sniffing out home-made bomb setups through chemical sensors placed in city sewer systems. Under the scenario, if the sensors do find traces of explosives, an alarm is sounded, and a special police team swings into action with a with a high resolution sensing unit, conducting a search to pinpoint the site.
