Engineers develop bio-machine nose that can “sniff” and classify odors
Engineers from Brown University in Rhode Island have invented a small, low-cost sensor device which is able to classify odors using input from a mimicked “sniffing” action. It’s called TruffleBot, and it’s here to raise the bar on electronic “noses”. It also works with Raspberry Pi, an inexpensive mini-computer popular with electronics hobbyists, students, and others in the “maker” crowd.
Generally, an electronic nose is a device comprising several chemical sensors whose results are fed through a pattern-recognition system to identify odors. In traditional devices, the chemical responses alone are used for classification. The engineers behind this invention, however, decided to incorporate non-chemical data to account for the mechanics of the smell process used in nature for a better result. Their experiment proved successful with an approximate 95-98% rate of accuracy in identification compared to about 80-90% accuracy with the chemical sensors alone.
According to the inventors’ published paper, the guiding knowledge that made TruffleBot so useful in odor detection was this: Different smells have different impacts on the air around them, and measuring the variations enables more accurate identification. Did you know that beer odor decreases air pressure and increases temperature? The changes are slight, but TruffleBot can sense them.
This is where the “sniffing” comes in. The device uses air pumped through four obstructed pathways before sending it through chemical and non-chemical sensors. Odors impact the air surrounding them, and the movement of the air through obstacles (“sniffing”) enables the odors’ impact to be more accurately measured.

So, where exactly would one need an electronic nose? Everywhere. Devices with the chemical sensing ability are being used in agriculture, military, and commercial applications to identify all sorts environmental data. Essentially, electronic noses are useful in any industrial application that has odor involved.
Nasal Marketing
Did you know that it’s possible to trademark a smell in the United States? It’s not easy to accomplish given the somewhat difficult requirements to meet, but a few such things exist. The fact that Play-Doh, a product whose smell is probably one of its most distinct features, was granted a trademark for the scent only this year is testament to the difficulty of obtaining such a mark. However, the fact that some companies have found enough incentive to make sure only their company can give your nose a particular chemical experience tells a lot about that sense’s importance from a marketing perspective.
On one hand, utilizing smell in marketing might seem a little manipulative. After all, creating an air freshener that reminds someone of a beloved, deceased relative on purpose might not seem like a particularly ethical way to target their money. On the other hand (or bigger picture), however, the motivation for marketers to use scent as a tool involves a sort of “chicken or the egg” question.
To summarize part of an article in the journal Sensors on the role scent plays in society and commerce, the aroma of products has a direct impact on their appeal to customers and thus, the success of the product. In fact, a change in a product’s formula that impacts its smell can, and often has had, devastating sales results. In other words, it’s not enough for a company to create a good product; it has to be a good smelling product.
Hacking the Human Nose
It’s probably no surprise that the commercial industry has categorized consumer preferences when it comes to smells. As the first sense fully developed after birth, our noses link us to things like memories, emotions, and chemical communication (think pheromones). Is it any wonder, then, why businesses might be interested in the functionality of the organ that is doing the receiving?
Turns out, there’s an enormous amount of science behind “hacking” a nose. Identifying smells is more than just categorizing chemical mixtures as “floral” or “masculine”. The multitude of chemical combinations available generates such a vast amount of data that scientists have implemented computer neural networks to analyze and classify it. Also, the actual mechanics of smelling something impacts the way the smell is received and processed in the brain. Computers and scientific instruments come in handy there as well. To really get to the core of human response to an aroma, lots of non-human tools are needed, and this is essentially where the TruffleBot fits in the greater realm of “olfactory” science.

More Than Just Your Money
Perhaps one of the most innovative uses found for electronic noses is in disease research. One of the limitations of human smell is its overall weakness. A dog’s sense of smell is around 40 times better than a human’s, and a bear’s is a whopping 2,100 times superior to ours. That said, when researchers learned that certain diseases give off certain odors, the human nose wasn’t exactly the first choice to utilize in sensing them.
An electronic nose makes good use of the simple fact that organic matter releases chemicals into the air. For example, when a plant has been impacted by a fungus, the changes brought on in the plant’s structure release what’s called “volatile organic compounds” (VOCs). These VOCs can be detected by the sensors in an electronic nose and then provide information on the type of disease present without destroying the plants being tested.
Humans have some amazing things to gain from electronic noses, too. Using sensors to process odors from VOCs, things like digestive diseases, kidney diseases, and diabetes, among many others, are all receiving scientific attention for non-invasive diagnosis by these types of devices. With improvements brought on by inventions like TruffleBot, especially combined with its low-cost and resulting accessibility, a future involving remote diagnoses for any number of illnesses and diseases seems more possible every day.

Tesla hints it could see ‘a few more vehicles’ released soon
Denholm said on CNBC yesterday that “we do have a few other vehicles coming out.”
Tesla Board Chair Robyn Denholm hinted the company could see “a few more vehicles” coming out and being released soon, although there is no indication of what could be on the way based on her comments.
However, Tesla has hinted toward several potential releases in the coming years, as other executives, including Chief Designer Franz von Holzhausen, have talked briefly about what could be on the way.
Denholm said on CNBC yesterday that “we do have a few other vehicles coming out.”

It was a vague and almost cryptic sentence, as, in all honesty, it was not completely clear whether she was talking about recent releases that are just making their way to market, like the Model 3 and Model Y “Standard,” or new vehicles altogether.
Nevertheless, it’s worth dissecting.
Tesla “Standard” Models
On October 7, Tesla launched the Standard Model 3 and Model Y, stripped-down versions of their now “Premium” siblings. The Standard trims lack premium features like leather seats, a rear touchscreen, and a glass roof, among other features.
These cars are just starting to be delivered for the first time, so it is possible that Denholm was referring to these cars.
Potential Model 2 Hint?
There has always been a looming vehicle model that many Tesla fans and owners have been intrigued by: the Model 2.
This car was hinted at being the $25,000 model that Tesla was rumored to be developing, and many thought that was the vehicle that would be released earlier this month, not the Standard Model 3 and Model Y.
Instead, the Model 2 could be something that would enable Tesla to reach an entirely new consumer base, including those who are not able to swing the payment for the company’s more premium offerings.
It seems Tesla will have to launch some sort of extremely affordable model in the future, and with the Cybercab being slotted at that rough price point, it would not be out of the question for it to be in the realm of possibility for future releases.
It’s worth noting, however, that it is probably unlikely this will happen. Tesla is so deadset focused on autonomy, it seems Cybercab would take extreme precedence over the unconfirmed “Model 2.”
Cybertruck-inspired SUV
Tesla fans have been begging the company to develop a full-size SUV that would compete with the Ford Expedition or Chevrolet Tahoe, but the company has not given any indication that this would be something it would build.
Nevertheless, there was a very subtle hint in a recent promotional clip that showed a Cyber SUV mock-up placed strategically next to a clay model of a Model 3:
The Model X is simply not what people want when it comes to an SUV, as it does not have the seating capacity and cargo space that many need with a full-sized SUV.
This issue, in particular, has been one that has been extremely relevant to the company’s future lineup as consumers have shown they would be interested in a Tesla vehicle that fit this description.
Additionally, von Holzhausen said in September that a Cyber SUV or a smaller electric pickup with a more traditional design is “definitely things we’ve considered…We’re working on so many innovative and fun things.”

Investor's Corner
Tesla enters new stability phase, firm upgrades and adjusts outlook
Dmitriy Pozdnyakov of Freedom Capital upgraded his outlook on Tesla shares from “Sell” to “Hold” on Wednesday, and increased the price target from $338 to $406.
Tesla is entering a new phase of stability in terms of vehicle deliveries, one firm wrote in a new note during the final week of October, backing its position with an upgrade and price target increase on the stock.
Dmitriy Pozdnyakov of Freedom Capital upgraded his outlook on Tesla shares from “Sell” to “Hold” on Wednesday, and increased the price target from $338 to $406.
While most firms are interested in highlighting Tesla’s future growth, which will be catalyzed mostly by the advent of self-driving vehicles, autonomy, and the company’s all-in mentality on AI and robotics, Pozdnyakov is solely focusing on vehicle deliveries.
The analyst wrote in a note to investors that he believes Tesla’s updated vehicle lineup, which includes its new affordable “Standard” trims of the Model 3 and Model Y, is going to stabilize the company’s delivery volumes and return the company to annual growth.
Tesla launches two new affordable models with ‘Standard’ Model 3, Y offerings
Tesla launched the new affordable Model 3 and Model Y “Standard” trims on October 7, which introduced two stripped-down, less premium versions of the all-electric sedan and crossover.
They are both priced at under $40,000, with the Model 3 at $37,990 and the Model Y at $39,990, and while these prices may not necessarily be what consumers were expecting, they are well under what Kelley Blue Book said was the average new car transaction price for September, which swelled above $50,000.
Despite the rollout of these two new models, it is interesting to hear that a Wall Street firm would think that Tesla is going to return to more stable delivery figures and potentially enter a new growth phase.
Many Wall Street firms have been more focused on AI, Robotics, and Tesla’s self-driving project, which are the more prevalent things that will drive investor growth over the next few years.
Wedbush’s Dan Ives, for example, tends to focus on the company’s prowess in AI and self-driving. However, he did touch on vehicle deliveries in the coming years in a recent note.
Ives said in a note on October 2:
“While EV demand is expected to fall with the EV tax credit expiration, this was a great bounce-back quarter for TSLA to lay the groundwork for deliveries moving forward, but there is still work to do to gain further ground from a delivery perspective.”
Tesla has some things to figure out before it can truly consider guaranteed stability from a delivery standpoint. Initially, the next two quarters will be a crucial way to determine demand without the $7,500 EV tax credit. It will also begin to figure out if its new affordable models are attractive enough at their current price point to win over consumers.

Tesla preps for a harsh potential reality if Musk comp vote doesn’t go to plan
A successful vote for Tesla would see the compensation package get approved. But there is always the possibility of a rejection, which would likely see Musk leave the company.
Tesla could be forced to look for a new CEO in the coming months, as a crucial November 6 Shareholder Meeting vote will determine whether Elon Musk will stick around.
A major vote is coming up at the 2025 Tesla Shareholder Meeting, as investors will determine whether Musk should be given a new compensation plan that would award him up to $1 trillion and more than one-fourth of the total voting power within the company.
Tesla board chair reiterates widely unmentioned point of Musk comp plan
A successful vote for Tesla would see the compensation package get approved. But there is always the possibility of a rejection, which would likely see Musk leave the company.
“My fundamental concern with regard to how much voting control I have at Tesla is if I go ahead and build this enormous robot army, can I just be ousted at some point in the future? That’s my biggest concern,” Musk said at last week’s Earnings Call. “That’s what it comes down to in a nutshell. I don’t feel comfortable wielding that robot army if I don’t have at least a strong influence.”
Tesla Board of Directors Head Robyn Denholm has been on somewhat of a PR tour over the past few days, answering questions about the compensation plan, which is among the biggest issues currently for the company.
Denholm told Bloomberg yesterday that Tesla investors need to be prepared for Musk to abandon ship if the package is not approved, which brings on a new question: Who would take over the CEO role?
That is a question Denholm also answered yesterday, bringing forth the conclusion that Tesla would not look for an outside hire if Musk were to leave the company. Instead, it would promote someone internally.
The way it was reported by Bloomberg and Reuters seems to make it seem as if Tesla is preparing for the worst, as it states the company “is looking at internal CEO candidates,” not preparing to do so.
Of the executives at Tesla who immediately come to mind as ideal candidates for a potential takeover should Musk leave, Tesla China President Tom Zhu and Head of AI Ashok Elluswamy both come to mind. Zhu has monumental executive experience already, as he was appointed to the role of Senior VP of Automotive back in December 2022.
He then returned to China in 2024.
It seems Tesla wants to align its future, with or without Musk, on the same path that it is currently on, and internal candidates might have a better idea of what that looks like and truly means.
