Cell Phones That Can Smell Danger
Abstract:
The Cell-All program began in October 2008 and the DHS is now funding work with NASA and San Diego-based companies Qualcomm and Rhevision. Qualcomm is working on miniaturization and commercialization; scientists from the Center for Nanotechnology at NASA's Ames Research Center are working on chemical sensing and researchers from Rhevision have developed a powerful lens that that can "read" the chemical the phone is sensing.
Rhevision's CEO Gary Shields says they are working in tandem with scientists at UCSD to develop this technology. Rhevision is producing something very different than what we generally think of as a lens--a very small, fluid lens that would be used in conjunction with a porous silicon artificial nose developed in the lab of UCSD Professor Michael Sailor. Nanoparticles in that artificial nose change color in response to different chemicals. Rhevision's fluid lens will identify the change and then it will be processed by a software algorithm, says Shields, written specifically to analyze the chemical.
