University of Hertfordshire researchers have created an electronic nose that can identify smells in tens of milliseconds using standard metal oxide sensors in an novel way. The micro-machined sensors ...

A portable ‘electronic nose’ that detects the signature gases produced by the common problematic gut pathogen Helicobacter pylori has been developed by researchers in Voronezh, Russia 1.

To make an electronic nose, a chemical receptor for the molecule-to-be-sensed needs to be bonded to the graphene channel, which is what Tokyo Tech is doing. What sets this project apart, is that the ...
