Smell, a sense that is often overlooked, plays a vital role in our lives. It allows us to taste food, discern danger, and even perceive emotions. However, the human sense of smell has limitations, especially in complex odor environments. However, this dilemma seems to have taken a new turn in the February ** dynamic incentive plan. The Department of Mechanical Engineering at Tsinghua University has made significant progress in the research of electronic nose bionic smell, and this innovative research result may completely change our understanding of smell! 
For a long time, electronic nose research has been trying to mimic the human sense of smell in order to achieve accurate identification of smells. However, due to the limitations of gas sensor technology, electronic noses are still difficult to match human olfactory sense in complex odor recognition and multi-odor classification. However, this new study from Tsinghua University breaks this deadlock!
The researchers have proposed a biomimetic sniffing strategy called Multiple Overlapping Sniffs (MOSS). This strategy innovatively introduces multiple overlapping sniffs by imitating the sniffing methods of professional sommeliers, so that the sensor array of the electronic nose generates time-series signals with rich dynamic features, so as to improve the perception and identification ability of different gases.
In the experiment, the researchers used an electronic nose composed of four CTL sensors to detect six spirits. By comparing the sampling results of the traditional single injection method and the MOSS strategy, it was found that the MOSS strategy could increase the accuracy of the electronic nose to 81 for the identification of 6 spirits94% to 9583% for high accuracy of different spirits!
In addition, the experiment further proved that the MOSS strategy has a significant effect on the odor recognition ability of electronic nose. Even under the constraints of only 2 CTL sensors to detect 6 spirits, the electronic nose of the traditional single-injection method can only achieve 6111% recognition accuracy; The MOSS strategy can make this electronic nose achieve 9167% recognition accuracy!
This research result not only proves the great potential of the MOSS strategy in electronic nose bionic olfaction, but also opens up a new path for future olfactory bionic research. Maybe one day, we will be able to use this bionic sniffing strategy to truly realize the accurate perception and recognition of odor by electronic noses, making our lives more convenient and beautiful!
Of course, there are still many areas for further exploration and refinement in this research. For example, how can the sensitivity and stability of gas sensors be further improved? How can this biomimetic sniffing strategy be applied to the wider field of odor detection? These questions require us to study and ** deeply.
Overall, this study provides us with a whole new perspective on olfactory biomimetic research. We have reason to believe that with the continuous deepening of research and the development of technology, electronic nose bionic sniffer will play an increasingly important role in the future life. Let's look forward to this day!
