‘Digital smell’ technology could mean you can send smells via online chats, scientists claim | Daily Mail Online

Fruity, woody, or minty! ‘Digital smells’ sent via electrodes placed inside your nose could let you transmit ODOURS in messaging and dating apps

• Researchers claim to have created fruity, woody and minty ‘electric smells’
• They did this by putting electrodes inside participants’ nostrils 
• This stimulated electrical currents behind the nostril where neurons were found
• However, critics say that smells might not have been created by electricity 

‘It is part of a whole, integrated virtual reality or augmented reality’, lead researcher Adrian Cheok who is the director of the Imagineering Institute in Malaysia told NBC.

‘So, for example, you could have a virtual dinner with your friend through the internet. You can see them in 3D and also share a glass of wine together’, he said.

Researchers created ten different odours for the 31 participants involved in the research.

Dr Cheok believes that one day odours will be sent in digital form over the internet – although he says that it might still be decades away.

The recipient could receive them by wearing glasses or goggles with electrodes in them.

‘The next stage is to produce it in a more controlled manner, and this will allow for people to develop software and products to generate electric smell’, Dr Cheok says.

He believes it could also restore smell to people who have lost it due to illness or an accident.

However, critics say that smells might not have been created by electricity.

Joel Mainland, a neuroscientist at the Monell Chemical Senses Centre told NBC that although it could be possible to create odours using electrical stimulation that might not have happened in this study.

‘If you are asking someone if something smells, they have a strong bias to say yes even where there is no odor’, he said.

Earlier this week, scientists said that zapping the brain by placing electrodes inside the nostrils could bring back someone’s lost sense of smell.

Being able to regain smell would be a breakthrough for millions, as figures estimate up to five per cent of people are unable to process scents.

Doctors at Massachusetts Eye and Ear tested the method on five patients who could already smell. It is the first time the sense has been stimulated this way.

The scientists believe the results open the door for a cochlear implant for the nose.

By placing electrodes in the nose, the nerves in the olfactory bulb were stimulated, and information was sent to the deeper regions of the brain.

Some cases of loss of smell can be treated by caring for an underlying cause, such as blocked sinuses or swelling, where the nasal passage is obstructed and smells can’t reach the brain.

In more complicated cases, the sensory nose may be damaged due to head injury, a virus or ageing, which can lead to anosmia – complete loss of smell.

There are currently no proven therapies for this, but the study proves there are options on the horizon.

Of all the useless projects undertaken by humanity, few have been more difficult, futile, and unpleasant than artificially creating smell, either through electrical impulses or by pumping in smells directly into a room (like the ill-fated Smell-O-Vision). Though smells can trigger emotions and even memories, nobody is really clamoring for a piece of technology that lets you smell someone you’re video-chatting with or sample a catalog of virtual smells (unless it’s one of those fancy air fresheners). Nevertheless, a team of researchers in Malaysia is forging ahead with digital smell technology, and they claim to have made some progress.

During the experiments, 31 participants had an electrodes inserted in their nostrils, which stimulated the receptors in the nose that send signals to the brain to create a sensation of smell. According to the Imagineering Institute, which conducted the study, the researchers were able to evoke 10 different artificial scents, though they weren’t able to control which one the participants smelled.

According to Adrian Cheok, one of the researchers associated with the study: “It’s not just about the smell. It is part of a whole, integrated virtual reality or augmented reality. So, for example, you could have a virtual dinner with your friend through the internet. You can see them in 3D and also share a glass of wine together.”

However, some scientists have doubted the findings of the study. One of them is Charles Spence, of the University of Oxford, who told Mach: “Any everyday smell will probably activate tens or hundreds of receptors. If you have only got one electrode in the nose, no matter what frequency rate or intensity (of electrical current you use) you are not going to be able to stimulate enough receptors to deliver a (perception).”

Joel Mainland, of Monell Chemical Senses Center in the United States, also pointed out that people may believe they can smell a faint odor when they’re told they should be smelling one. According to Mainland, the Malaysia study doesn’t adequately account for this issue.

Either way, we’re not holding our breath (or noses) for the day when you can email someone the scent of a sandwich.

Researchers envision a cochlear implant–like device for the nose to give people with impaired olfaction a sense of smell.

“Our work shows that smell restoration technology is an idea worth studying further,” says coauthor Eric Holbrook of Massachusetts Eye and Ear Infirmary in a press release. “The development of cochlear implants, for example, didn’t really accelerate until someone placed an electrode in the cochlea of a patient and found that the patient heard a frequency of some type.”

Holbrook and colleagues enrolled five subjects in the study who were able to smell. Three of them reported perceiving odors not actually present when the researchers stimulated different parts of their olfactory bulbs with electrodes inserted through the nose, a procedure the study authors say caused “minimal discomfort.” Subjects described the smells as “onion-like,” “antiseptic-like,” “sour,” “fruity,” or simply “bad.”

The finding follows a report earlier this year that electrically stimulating structures high up in the nasal cavity produced smell sensations. The scientists who conducted that study at Malaysia’s Imagineering Institute aim to one day transmit smells electronically, reportes IEEE Spectrum—for example, to give restaurant-goers a whiff of dishes on the menu as they decide what to order.

As in the Massachusetts Ear and Eye study, the Imagineering Institute researchers weren’t able to control which odor the subjects perceived. The Malaysian team suggests the digital smells could be transmitted through a noninvasive headset, rather than with electrodes up the nose, which their volunteers found quite uncomfortable. As coauthor Kasun Karunanayaka tells IEEE Spectrum, “A lot of people wanted to participate, but after one trial they left, because they couldn’t bear it.”

Future video chats might include smell along with sight and sound

‘Digital smell’ technology could let you send ODOURS in dating apps

Researchers have been able to evoke 10 different virtual smells, including fruity, woody and minty

It’s one of the most evocative senses, and now your sense of smell you be stimulated through odours sent in online chats.

Researchers from the Imagineering Institute in Malaysia have developed ‘digital smell technology’, that could let you send smells online.

Speaking to NBC News, Adrian Cheok, one of the researchers behind the system, said: “It’s not just about the smell.

“It is part of a whole, integrated virtual reality or augmented reality.

“So, for example, you could have a virtual dinner with your friend through the internet. You can see them in 3D and also share a glass of wine together.”

Normally, odours are transmitted by airborne molecules that enter your nose.

But in this system, the researchers used electrodes in the nostrils to deliver weak electrical currents to simulate smells.

During tests on 31 participants, the team was able to evoke 10 different virtual smells, including fruity, woody and minty.

Future video chats might even transmit smells: See how

Modern-day internet messaging platforms (WhatsApp, Facebook Messenger et al) have re-defined end-to-end conversations.

You can call a friend anytime to see what they are doing or where they are.

But, in order to make these conversations even more immersive, a group of scientists is exploring the possibility of transmitting smell via chats. Yep, SMELL!

Here’s how that could be a reality.

Tech

How smell could be transmitted on chat?

At present, no technology allows us to convey smell on internet-based chats.

However, in recent experiments, scientists were able to trigger different smell senses electrically, something that suggests a system like that might be a reality in the future.

They have envisioned a nose-like device that would sense odors and transmit them digitally to the receiver, along with sights and sounds, NBC News reported.

Experiment

Here’s how they electrically triggered a sense smell

A sense of smell is created when air molecules enter the nose and trigger specialized nerve cells, which deliver sensory impulses to the brain.

The scientists used the same technique, but instead of using air, they employed weak electrical currents to trigger these neurons.

They placed electrodes in the nostrils of 31 test subjects to deliver currents where the neurons are found.

The result

The subjects sensed different odors, but with no control

The resulting, electrically triggered impulses, led the subjects to smell virtual creations of 10 different odors, including fruity, minty, and woody.

Though they were not able to control which odor the subjects experienced, the team thinks the tech could be advanced to create a digital smell tech, where odors transmitted from that nose-like device would be received with some sort of glasses or goggles.

EVOKING VIRTUAL ODORS

In real life, odors are transmitted when airborne molecules waft into the nose, prompting specialized nerve cells in the upper airway to fire off impulses to the brain. In the recent experiments, performed on 31 test subjects at the Imagineering Institute in the Malaysian city of Nusajaya, researchers used electrodes in the nostrils to deliver weak electrical currents above and behind the nostrils, where these neurons are found.

The researchers were able to evoke 10 different virtual odors, including fruity, woody and minty.

The scientists couldn’t control which odors the subjects experienced, and they’re under no illusion that people will want to stick wires up their nostrils each time they have a video chat.

But Cheok, who is also the institute’s director as well as a professor at the City University of London, foresees a day when odors might be sensed by a sort of electronic nose (similar devices are now used in food-processing plants), sent in digital form over the internet and delivered to the recipient not via wires in the nose but via electrode-studded glasses or goggles.

“This stage was more exploratory,” Cheok said of the research. “The next stage is to produce it in a more controlled manner, and this will allow for people to develop software and products to generate electric smell.”

Cheok said it might take decades before the sorts of devices he envisions are ready to use. But he thinks devices that convey pre-programmed odors for entertainment applications — for example, to give moviegoers the generic scent of burnt rubber as they watch a car chase in an action movie — might be available sooner, perhaps within 15 years.

Electric smell technology could find applications beyond entertainment and personal communications. If it does prove feasible, it might be used to restore a sense of smell in people who have lost it as a result of illness, injury or inborn abnormality, said Joel Mainland, an olfactory neuroscientist at the Monell Chemical Senses Center in Philadelphia.

“I think there are medical implications for a certain class of people who have lost their sense of smell, but not everybody,” Mainland said.

A FLAWED STUDY?

Mainland added that it should be at least theoretically possible to evoke specific odors via electrical stimulation. He compared this approach to cochlear implants, which electrically stimulate the nerve that carries sound signals to the brain to restore limited hearing to deaf people. “It’s not a natural stimulation,” he said of cochlear implants. “It seems like it shouldn’t work.”

It’s possible a smell-restoring device could function in a similar manner, he said. “If you start playing something that is correlated to smells that are coming in, people’s brains will be able to decode what is going on.”

But Mainland is critical of the Malaysian study, saying it’s possible that the smells the subjects reported may not have been produced by electricity. “I can give you an empty jar to sniff when you don’t have anything up your nose, and sometimes you would report a faint odor,” he said in an email. “If you are asking someone if something smells, they have a strong bias to say yes even where there is no odor.”

The study failed to account for this possibility, he said.

Why do we think tiny things are cute?

You can’t smell the food in that review you’re reading on Yelp, but one day you might be able to.

Researchers at the Imagineering Institute in Malaysia are working on creating “digital smell.” One day they want users to be able to smell what they’re seeing when they use their digital devices. Right now, though, the process involves putting a cable up the user’s nose in order to stimulate certain neurons in the nasal passage.

In order to get people to think they were smelling something, the research team needed to deliver electric currents to the olfactory epithelium cells about 7 centimeters above and behind the nostrils. Most of the volunteers reported fragrant or chemical smells, although some also reported fruity, sweet, toasted minty, and woody odors.

The next step is to find a less invasive way to administer the electricity, such as a much smaller cable or by skipping the nose entirely and stimulating the brain instead.
