Traditional detection methods use a large, heavy laboratory equipment, but handheld detectors may soon be possible thanks to a new fiber composite.
The composite consists of a net of nanofibers that functions like the olfactory cilia of a dog’s nose, catching chemical molecules from the air. An alkane molecule will stick between the fibers, blocking the transfer of electrons between them and thereby signaling the presence of alkane vapors.
Sensors using this composite have a number of applications, including detecting pipeline leaks, airplane fuel leaks and in security systems.
Preventing Pipeline Leaks
Securing Airplane Fuel Tanks
Detecting IEDs
Alkane fuel, in the form of fuel oils such as diesel, is also the major component in improvised explosives, like the bomb used in the Oklahoma City Bombing of 1995. Integrating the sensor into security systems could prevent such attacks in future.
Vaporsens, the company which created the nanofiber-based sensor, plans to release the device to market in late 2017.
