Experience the future of the artificial olfactory with SmartNanotubes' revolutionary e-nose technology. Our Smell Board and Smell Inspector developer kits empower you to explore and integrate advanced odor-sensing capabilities into your products.
At the heart of these devices is the Smell iX16 detector chip, a cutting-edge sensor based on semiconducting carbon nanotubes. This 16-channel chip offers exceptional sensitivity to gases, odors, and volatile organic compounds (VOCs), all while consuming a mere 1 µW of power. Its compact design allows for versatile power options, including host devices, energy harvesters, or batteries, and can be tailored to meet specific application needs.
Our Smell Board and Smell Inspector kits are specifically designed for corporate clients. The developer kits provide a hands-on-opportunity to validate and experience our e-nose technology's potential for mass-market applications. By emulating the human olfactory system, these devices, when paired with the Smell Annotator App, can be trained and seamlessly integrated into a vast array of electronic and IoT applications.

While both the Smell Inspector and the Smell Board use similar sensor technologies, they are designed for different use cases. The Smell Inspector is a handheld device, ideal for short-term, portable usage in more domestic or experimental settings. It is easy to use and designed for quick, on-the-go measurements. On the other hand, the Smell Board is intended for more industrial and long-term monitoring. It is suited for continuous, stable operation in monitoring and corporate development scenarios. Although both devices are capable of performing short-term and long-term measurements, the Smell Inspector is optimized for mobility, while the Smell Board is better suited for fixed installations and rigorous data collection over extended periods.
SmartNanotubes e-nose technology does pattern recognition. Smell Inspector and Smell Board each contain four of our Smell iX16 detector chips with 16 channels of different modifications. Each scent (as well as each single gas) produces a unique pattern of 64 signals from the 64-channel sensor array. Every 1.8 s, the change in resistance on each of the channels can be recorded. These recorded patterns which correspond to different scents are fundamental to train a ML model.

We use Smell Annotator software to control, annotate and store measurements of Smell Inspector and Smell Board as well as to recognize annotated smells. Yes, you may sample a smell and extend your digital smell data collection to compare the stored smells with new readings.
A lot substances can be detected. Some tested gases and smells: ammonia, nitrogen monoxide, phosphine, carbon dioxide, hydrogen sulfide, ethanol, acetone, isopropanol, toluene, hydrogen peroxide, formaldehyde, 2,6-dimethaxy-phenol, 2-methoxy-4-vinylphenol, guaiacol, some perfumes, chocolate, wine, vodka, coffee, tee, lemon juice, onion, garlic, banana, orange, potato, meat, fish.
Our e-nose technology is highly sensitive. We have benchmarked the sensitivity of our detector chips with respect to some standard test gases. So, the limit of detection of our chips is below 90 ppb for NH3, 60 ppb for N02, 35 ppb for SO2. Most other substances and smells are reliable detectable at high-ppm concentration levels (thousands of ppm).
A mixture of smells is also another smell. The digital patterns for this particular mixture can be recorded as background smells in the same way as the other smells. The ML model will be able to interpret and to separate them to recognize the other smells.
No, Smell Inspector and Smell Board does not transmit smells. But our e-nose technology can be combined with other technologies that are able to release smells.
Yes, this is the idea. Our technology is both smell detector and multi-gas analyzer – as you define it to be! It is designed for qualitative detection and distinguishing of gases and smells.
Our e-nose technology is neither able to provide gas concentrations nor is it able to detect particles.
For first steps with the Smell Inspector and the Smell Board we provide a handbook and some reference examples for smell detection.
Our first research results on gas sensing were published here: L.A. Panes-Ruiz, et al. (2017), “Toward Highly Sensitive and Energy Efficient Ammonia Gas Detection with Modified Single-Walled Carbon Nanotubes at Room Temperature”, ACS Sens. 2018, 3, 79−86, DOI: 10.1021/acssensors.7b00358.
The biggest difference between conventional single gas detection and our gas/smell detection technology is that the latter is based on pattern recognition. A specific digital pattern produced by the sensor array in response to a gas or a smell is compared to the stored patterns. The detectors are based on nanomaterials which make the detectors highly sensitive (see the question on sensitivity). The power consumption at the detector is below 0.001 mW which is several orders of magnitude lower than that of e.g. MOX sensors. Our detectors are less than 1 sq mm in size and the detector chips are very compact and can easily be integrated in various appliances. Moreover, thanks to our production technology the detector chips can be fabricated fully in house for an affordable price.
