A large scanner for a slim device the size of a stamp. being developed by GE Global Research To improve explosives and hazardous substances detection systems is a huge leap to integrate these devices almost anywhere and much more thoughtfully and economically.
The GE sensor, for which they are collaborating with the Technical Support Working Group (TSWG), an agency specializing in counterterrorism, is wireless and does not require batteries to operate. It is actually an RFID tag that is activated only in the presence of certain explosive or dangerous substances.
passive detection of hazardous substances
More technical details of this sensor, safety, have not been unveiled by GE, but have given up important data to understand its functioning: a new material developed by them that responds to the presence of certain “oxidizing” substances and which Able to integrate into one of the faces of the RFID chip.
The new sensor, which has an “expiration date” of months and is very cheap to manufacture, is ideal to be placed at places of loading or transit of goods, for example, and should be inactive and undetectable until a Don’t let the substance set off the alarm. The chip can read at a distance of up to 3-4 meters, depending on the needs and power of the antenna mounted on the RFID tag.
So far the new material specializes in explosives, but from GE, they believe, it will not be long until they manage to develop a new material focused on other substances that are more common bacteriological or chemical Allows passive detection of risks.
