In a groundbreaking study published in the *International Journal of Extreme Manufacturing*, researchers from the University of Science and Technology of China have unveiled a revolutionary approach to artificial multisensory devices. This innovation centers around the fabrication of carbon nanotube-based neuromorphic thin film transistor (TFT) arrays that can simulate both olfactory and visual senses, a significant leap forward in the realm of artificial intelligence and human-computer interaction.
The lead author, Nianzi Sui, emphasizes the potential of this technology, stating, “Our device not only mimics human sensory processing but also operates at an astonishingly low power consumption of just 25 attojoules for a single pulse. This opens up new avenues for flexible and efficient multisensory applications.” The research highlights the use of semiconducting single-walled carbon nanotubes (sc-SWCNTs) as channel materials, paired with a sophisticated photosensitive polymer. This combination allows the device to detect stimuli across a wide spectrum of wavelengths (from 280 nm to 650 nm) and operate effectively in temperatures ranging from 0 to 150 °C.
The implications of this research extend beyond theoretical applications; they hold significant promise for the construction sector. As industries increasingly integrate smart technologies into their operations, the ability to create devices that can recognize and respond to multiple sensory inputs could enhance automation and monitoring systems. For instance, construction sites could deploy these neuromorphic devices to detect environmental changes, such as the presence of hazardous gases or variations in light, thereby improving safety protocols and operational efficiency.
Moreover, the high I_On/I_Off ratio of up to 10^6 at low voltages (−2 to 0.5 V) allows these devices to mimic essential biological functions, such as synaptic plasticity. This capability could lead to the development of advanced robotic systems that navigate complex environments autonomously, a feature that could be particularly beneficial in construction projects where human oversight is limited or where conditions are hazardous.
Sui notes the unique ability of their device to simulate the recovery of olfactory senses, especially in the context of post-COVID-19 scenarios. “By integrating olfactory and visual inputs, we can create systems that not only recognize but also adapt to human needs and environmental factors,” he explains. This adaptability could be invaluable in smart buildings, where environmental sensors work in harmony to create more responsive and sustainable living spaces.
As the construction industry continues to evolve with the advent of smart technologies, the research conducted by Sui and his team could serve as a catalyst for developing more sophisticated, responsive systems. The potential for creating an interconnected environment that recognizes and reacts to multiple sensory inputs could redefine how we approach safety, efficiency, and sustainability in construction.
