Research scientists at the Georgia Institute of Technology have used inkjet technology to produce a device capable of detecting explosives, according to engadget.
Krishna Naishadham and Xiaojuan (Judy) Song created the prototype using technology developed by fellow researcher Manos Tentzeris. As The Recycler previously reported, he was able to use inkjet printers to create a sensor powered by ambient electromagnetic energy.
Naishadham and Xiaojuan have adapted the sensor to detect ammonia, a common ingredient in most home made explosives. This makes it particularly useful for detecting improvised explosive devices (IEDs) commonly used by insurgents and terrorists.
“This prototype represents a significant step toward producing an integrated wireless system for explosives detection,” said Naishadham. “It incorporates a sensor and a communications device in a
small, low-cost package that could operate almost anywhere.”
The tiny sensor devices are able to detect even trace amounts of ammonia, making it well suited for military use and other bomb detectors in dangerous situations.
The invention also displays the high level of versatility afforded by inkjet technology.
“Ink-jet printing is low-cost and convenient compared to other technologies such as wet etching,” Tentzeris explained. “Using the proper inks, a printer can be used almost anywhere to produce
custom circuits and components, replacing traditional clean-room approaches.”
