Researchers
from Japan Advanced Institute of Science and Technology (JAIST) and the
University of Southampton developed the Graphene-based sensor. It is a
device that can detect harmful air pollutants
at your house.
According to Gizmag,
the device can identify volatile organic compound (VOC) gas molecules
and the airborne CO2 molecules. Graphene is described as the single thin
layer of pure carbon that is linked and bonded together as hexagonal
honeycomb lattice. It is considered the thinnest and lightest material
and extremely sensitive in detecting chemical gases.
When VOC and CO2 molecules connect with the graphene and are then
released, the electrical resistance of the graphene is modified. The
sensor is capable of identifying those changes and determines any
substances that are visible in the atmosphere. Lab tests were conducted
and its prototype identified CO2 gas within minutes just when a gas was
released in the room.
