Researchers have developed a prototype wireless sensor capable of detecting trace amounts of a key ingredient found in many explosives. The device, which employs carbon nanotubes and is printed on paper or paper-like material using standard inkjet technology, could be deployed in large numbers to alert authorities to the presence of explosives, such as improvised explosive devices.
Researcher Krishna Naishadham says, "This prototype represents a significant step toward producing an integrated wireless system for explosives detection. It incorporates a sensor and a communications device in a small, low-cost package that could operate almost anywhere."
The resulting integrated sensing package can potentially detect the presence of trace explosive materials at a distance, without endangering human lives. The wireless sensor nodes require relatively low power, which could come from a number of technologies including thin-film batteries, solar cells or power-scavenging and energy-harvesting techniques.
"We are focusing on providing standoff detection for those engaged in military or humanitarian missions and other hazardous situations," Naishadham says. "We believe that it will be possible, and cost-effective, to deploy large numbers of these detectors on vehicles or robots throughout a military engagement zone."

And if you want to be among the FIRST to read Whitley’s new sequel to Communion, "Solving the Communion Enigma," you can PRE-ORDER it now. Once you have purchased the book, you’ll need to either forward the e-receipt or send as a jpg, screenshot (etc.) to the publisher. You will then receive an autoresponse that will include a link to a page where you can input your address. Tarcher will send a special "Communion Enigma" bookplate out to the recipients shortly before publication date. To learn more, click here.
