United States : GEORGIA TECH unveils chemical vapor-sensing device

June 26, 2014

Researchers of Georgia Tech have created a chemical vapor-sensing device.

Created by a Georgia Tech Research Institute (GTRI) team, the technology, is targeted at various applications in military, commercial, environmental, healthcare and other areas.

While an Radio-frequency identification (RFID) capability informs users about the existence and concentrations of those vapors wirelessly, the technology sees an arragy of sensors making use of carbon nanotubes and other nanomaterials to detect particular chemicals.

The RFID component, as it is based on programmable digital technology, can deliver enhanced security, dependability and range and much smaller size than previous sensor designs based on non-programmable analog technology.

The prototype device, which could be made through the use of aerosol-jet printing techniques, is 10 centimeters square.

GTRI senior research scientist Xiaojuan (Judy) Song said : "Production of these devices promises to become so inexpensive that they could be used by the thousands in the field to look for telltale chemicals such as ammonia, which is associated with explosives. This remote capability would inform soldiers or first responders about numerous hazards before they encountered them."
