Detect terrorist bombers with feces

Swedish scientists have developed a device that can be attached inside a waste pipe to detect explosive materials that help track down terrorist bombs.

The Swedish Defense Research Organization (FOI) has named the intelligent system as EMPHASIS . The device is essentially a sensor network that is installed above and below the ground, which can "sniff" the chemicals in liquid and evaporated gases.

According to the invention group, each of the sensors comprises "selective ion electrodes" , about 10 cm long and mounted in the flow of waste water in the waste plumbing system. If an unauthorized bomb maker discharges chemicals into the toilet or chemicals during the bomb making process that enters a person's blood and eventually occurs in their urine or faeces, they will pass through the Sensor.

The ions present in these chemicals passing through the electrodes of the sensor will change the voltage of the sensor's resistance. Such changes will be recorded and tracked thanks to specially designed software that tracks every trace, even the smallest of suspicious ions.

If ions are detected in large numbers, the ionic data, their relative positions based on the contact distance of the sensors, the time and the ionic content discovered will automatically be sent to one. command center.

Special teams equipped with infrared laser guns will then conduct a field scan to detect suspicious gas molecules and narrow the target area (suspected terrorist bombers) . Once the target area is narrowed, authorities will install additional sensors in the sewer to determine the exact location of the suspect.

The EMPHASIS system is the product of a project funded by the European Union to undermine the production of explosives. According to a statement on the FOI website, "the goal of the EMPHASIS project is to test a future intelligence system intelligence tool to detect and locate illegal bomb factories in the area. city".

The team has now successfully tested the new smart sensor in laboratory wastewater. They are expected to conduct EMPHASIS testing in the sewer system in the field next year.
