Latest Electronic nose Stories
redOrbit Staff & Wire Reports - Your Universe Online Japanese researchers have created two new automatons – a female humanoid and a dog robot – that alert those suffering from smelly body odor or bad breath, the Asahi Shimbun newspaper reported this week. The female robot, dubbed Kaori, resembles a woman's head and measures the operator's breath, declaring an "emergency" if it registers in the worst category. The dog robot, Shuntaro, growls when it detects stinky feet. The...
Michael Harper for redOrbit.com – Your Universe Online [ Watch the Video: Nanotech Device Mimics Dog’s Nose to Detect Explosives ] A dog’s nose is 1,000 times better at picking up scents than a human’s nose. Dogs have long been used to sniff out drugs and explosives at the nation’s borders and airports. As such, it only makes sense to model an electronic nose after the canine’s. The University of California at Santa Barbara (UCSB) has managed to do just that, creating an...
April Flowers for redOrbit.com - Your Universe Online No one denies that a sense of smell is important. People have trained themselves to smell the subtle differences in foods and wines and perfumes. We have trained dogs that can smell explosives and drugs and even the changes in a person's body when they are going to have a seizure. With this much emphasis on smelling, is it any wonder that someone has developed an electronic nose? Research by Nosang Myung, a professor at the...
Almost a century after telephone pioneer Alexander Graham Bell first popularized the idea of measuring smells, chemical vapor sensors ― "electronic noses" ― are being developed for use in diagnosing disease, detecting national security threats, and other futuristic uses. A new episode in the American Chemical Society's (ACS) award-winning Bytesize Science series takes viewers on a behind-the-science tour of a major lab that is developing affordable, easy-to-carry chemical vapor...
Chemical sensors are exceedingly good at detecting a single substance or a class of chemicals, even at highly rarified concentrations. Biological noses, however, are vastly more versatile and capable of discriminating subtle cues that would confound their engineered counterparts. Unfortunately, even highly trained noses do leave a certain ambiguity when relaying a signal and are not particularly suited for work in specialized situations like operating rooms. A new DNA-based chemical sensor...
Have you ever been disappointed by a cantaloupe from the grocery store? Too ripe? Not ripe enough? Luckily for you, researchers from the University of California, Davis might have found a way to make imperfectly ripe fruit a thing of the past. The method will be published on March 30 in the Journal of Visualized Experiments (JoVE). "We are involved in a project geared towards developing rapid methods to evaluate ripeness and flavour of fruits," said paper-author Dr. Florence Negre-Zkharov....
These findings have implications for automated environmental toxicity monitoring and transmitting scent digitallyWeizmann Institute scientists have 'trained' an electronic system to be able to predict the pleasantness of novel odors, just like a human would perceive them "“ turning the popular notion that smell is completely personal and culture-specific on its head. In research published in PLoS Computational Biology, the scientists argue that the perception of an odor's pleasantness is...
A new intelligent system has been developed to help identify terrorists carrying explosives. Sensitive electronic noses capture the smell of the explosives; the system processes the acquired data, correlates it with individuals' movements "¦ and ultimately tracks down the suspects.Literally hundreds of people are hurrying through the long airport corridor between Terminals A and B. Among them are two terrorists, who've hidden themselves in the crowd. They're carrying small containers of...
The use of an electronic smelling system capable of discriminating which tomatoes, melons or other products have a more attractive aroma is a particularly valuable aid for agro-food firms. However, existing electronic noses do not "smell" in the same way depending on the laboratory conditions, and these conditions change throughout the day and from one day to another. In order to overcome these fluctuations, researchers from the Agro-Food Quality Improvement Group at the Universitat Jaume I...
"Although e-noses already have many uses "“ such as detecting spoilage in the food industry and monitoring air quality "“ they are not as discriminating as biological noses," according to CSIRO scientist, Dr Stephen Trowell."Our efforts to improve e-noses recently received a boost following our development of a new system which enables us to compare technical sensors with biological sensors."We looked at how the most common type of e-nose sensors "“ metal oxide or "˜MOx' receptors...
