The Department of Homeland Security has publicly stated that they want cell phones to have the capability of detecting biological, chemical, and radioactive materials. Though the user could turn this function off, it would be on by default, making each cell phone user opt-out of this new idea.
Putting hazardous material sensors in commercial cell phones has been discussed in scientific circles for years, according to researchers in the field. More recently, the idea gained support among government agencies, and DHS said publicly in May that it wants businesses to start coming up with proposals.
While, in theory, it sounds like a good idea, it is worrisome that the DHS wants this sort of capability in the hands of the common man.
Cell phone sensors would continually test the air for harmful compounds and digitally relay any information to a central monitoring system if they find anything amiss.
In essence, this gives the government yet another excuse to be able to track an individual, all in the name of protecting innocent Americans.
The cell phone sensors might be less sophisticated than highly advanced ones some developers are fitting into hand-held models, but they would make up for it in what Kelly called “ubiquitous detection.”
If just one went off, it could be ruled a false positive, he said. But if several detected a harmful compound, emergency workers would know there was a problem, triangulate the phone’s location react to the situation.
Currently under the name Cell-All, this technology is still in its infancy. Though researchers have been toying with the idea for years, there has been little development of the technology. Several prototypes do exist, but they are costly. However, with keen interest from the DHS, the idea could be kick-started to life.
Pennsylvania-based eV Products, which manufactures x-ray and gamma ray detection equipment, and Gentag Inc., a company with offices in Washington, D.C., and the Netherlands that designs radio frequency identification (RFID) and other sensors for cell phones are stepping up to the plate. For now, their primarily goal is to create a cell phone-based platform that detects only radiation.
Dartmouth College has done sensor and networking development for the government in the past, and is currently working on MetroSense, a system that can track the movements of people over large areas in real-time. George Cybenko, one of the engineering professors on the project, said “several technological breakthroughs would have to happen” before Cell-All would work.
There are also many problems that prevent widespread use of such technologies. GPS doesn’t work well indoors, making it unreliable to detect and pinpoint locations inside. There is the cost of tiny sensors that fit into a cell phone, as well as battery power to consider. Still, others are finding obstacles to creating accurate sensors, due to the natural occurring radiation on Earth.
One particular challenge for eV Products researchers has been coming up with a sensor that can tell the difference between harmless and dangerous radiation, Smith said.
In the chemical and biological worlds, he said, dangerous compounds are rare. But, “in contrast, radiation is a problem, because when you pick up radiation in the world, 99 percent of it is supposed to be there.”
Scientists are already floating around the possibilities of swapping out sensors to detect different things, as well as devices with sensors permanently attached. Much like the many different types of cell phone covers, you could keep up with the latest fad by swapping out your sensor. Today biological sensors, tomorrow radioactive.
Martin Dudziak, founder, chairman and chief science officer of Tetrad Technologies Group, Inc., has said they already have the technology for joining the sensors to networking.
Dudziak said he wants to integrate a cell phone sensor feature into Nomad Eyes, a digital network his company created. Tetrad encourages people with camera- and Internet-enabled cell phones to send data to Nomad Eyes, which will then analyze it and forward it to the proper authorities.
He said his company already has a hand-held biological sensor that can detect tuberculosis, influenza, salmonella, e. Coli and hepatitis, and is ready to put similar hardware in phones.
If all this sounds familiar, maybe it’s because you’ve watched too much Star Trek and are realizing that this is a primitive form of a tricorder.
There are also other problems, such as calibration of the units that will ultimately need to be dealt with.
Bob Durstenfeld, director of corporate marketing for RAE Systems Inc., a San Jose, Calif., company that makes hand-held sensors, as well as systems that have been used at Super Bowls and Presidential inaugurations, said sensors will not stay reliable without frequent service.
Durstenfeld added that he does not see the advantage of a cell phone network over a simpler solution, such as putting sophisticated biological, chemical and radiation sensors on all first-responder vehicles.
Ultimately, the issue over privacy concerns will need to be addressed. While this could be a useful, first response technology, intrusion into the privacy of individuals will have to be considered before implementation can occur. Americans already have many intrusions into their lives, such as CCTV cameras, that they cannot control.
We shouldn’t get too excited over this new technology but we should keep an eye on it. It isn’t quite practical, yet, but there will be a market for it. Right now, there are many initiatives that need humans that can, and will, be implemented long before your cell phone detects radiation.
