GE Develops Cost Effective RIFD Tags to Detect Explosives


Published Date : Feb 25, 2015

After days of relentless research, GE Global Research has finally developed the next generation sensors for cargo shipping. These cost effective sensors will help to detect the chemicals used in explosives or any other kind of hazardous materials at shipping ports. 

The company partnered with the Technical Support Working Group (TSWG), the U.S Interagency Program that delves into the research and development of measures to counter terrorism, Quantum Magnetics, a Morpho Detection subsidiary and KemSENSE, an annex of Vener8 Technologies to develop this new and powerful sensor. Based on radio frequency identification technology (RIFD), a lineage of GE, these sensors are powerful wireless medium that will detect as well as quantify chemicals of interest, present in small amounts, in the presence of compound impedances without accelerating the levels of complexities, cost, or size. 

The GE’s RIFD sensors are coated with sensing compounds that responds to oxidizers and explosives. These sensors do not require battery. The tags are most often in the size of a penny and can be deployed on different kinds of surfaces. Mostly, the sensors are placed on the outside of a container. In case the sensing material detects the presence of dangerous oxidizers or explosives in the air it will alter its electronic properties to trigger the RIFD tag. This will send alert to a reader that may be of the size of a telephone. 

Principal Scientist at GE Global Research who is also the lead investigator of the project said that the sensors developed are very powerful and they have the capability of dramatically increasing the accuracy and enhancing the limits of detecting the potential presence of any chemical threats at shipping ports.
