An olfactory sensor is a sensor which detects chemical changes in the air, in a similar way to an organic nose. They are often used in augmented reality systems to augment visual feedback of the status of an area. They may also be used by a person in long-term VR interface, to detect changes in health status.

The BOND nose is a project working at the opposite end of the spectrum to most attempts to integrate electronics with the sense of smell. Rather than deciper how the brain does it, BOND places olfactory proteins on an integrated chip, and decodes the signals itself. The goal? A hand-held, artificial nose more powerful than a dog's but with the same wide olfactory range.
How do you set up a sensor web in a forest? Solar power is useless thanks to the canopy. Wildlife will get tangled up in the cables, as will people trying to manage the forest. Units need to be monitored for damage requiring dedicated staff on-site. If only we could fix all these problems, we could use sensor webs in remote areas... What's that? They're all fixed, you say?
German researchers have made advances in the sensor systems that detect if a window is open or closed, by using of all things, a heavily modified washing machine tumble sensor. It detects movement ofthe window flawlessly, by the exact same means.
Researchers at the University of California demonstrate how to turn thousands of private iPhones into a single real-time sensor web, with the help of a plug-in sensor, and an app that provides enough real immediate benefit to the iPhone users thatthey'll run it much of the time. In this case, air quality sensors, complementing (and exceeding) the capabilities of the traditional air quality weather stations.
A technological scent sensor that works in almost the exact same manner as a bog's biological nose has been developed by researchers at the University of California. The sensor, the size of an adult male fingerprint, uses microfluidic nanotechnology to mimic the biological mechanism behind canine scent receptors. The device is both highly sensitive to trace amounts of certain vapour molecules, and able to tell a specific substance apart from similar molecules.
A novel take on the sensor web has been unveiled by US firm Xhale incorporated, consists of a wireless network of soap dispensers, which contain sensors capable of detecting whether the hand waved under it, has recently been sanitized or not.
A layperson-designed article from the American Society for Neuroscience, explaining the basics of how the sense of smell functions, from a chemical and neural point of view.
A new sensor, is able to differentiate true darkness from fog or smoke, for vehicle navigation. Even better, the developers have listened, and efforts to make it cheaply for all cars are well under way.
Sweeping an empty patch of ground to ensure it remains empty, seems an odd job for a complex sensor web. Yet, if a passenger jet strikes debris during landing or take off, it spells disaster for all aboard.
AMPERE is one of the many dedicated networks necessary to protect and grow a fledgeling sensor web. Looking down from space, 66 satellites monitor the Earth's electromagnetic field - and watch for spikes.

US researchers believe they are a step closer to developing a sensor which mimics the workings of the human nose. The MIT team claim to have overcome one of the biggest hurdles - mass production of proteins called "olfactory receptors".
A multidisciplinary research team with eight European partners is collaborating under a EU-funded project called Bioelectronic Olfactory Neuron Device, dubbed BOND. Their aim is to develop a very sensitive and selective device that can dete...
A new study finds that mice have a distinct neural subsystem that links the nose to the brain and is associated with instinctually important smells such as those emitted by predators. That insight, published online this week in Proceedings ...
Despite the striking aromatic differences between coffee, peppermint, and pine, a new mapping of the nose's neural circuitry suggests a haphazard patchwork where the receptors for such disparate scents are as likely as not to be neighbors....
People with psychopathic tendencies have an impaired sense of smell, which points to inefficient processing in the front part of the brain. These findings by Mehmet Mahmut and Richard Stevenson, from Macquarie University in Australia, are p...
