There are often discussions about losing the ability to smell or taste due to the new coronavirus, but even though we usually do not pay much attention to our sense of smell, it provides us with a remarkably diverse range of information in our surroundings, not just related to food and drink. For example, the first indication of a fire in an unseen location or a malfunctioning device can often come from smell. Additionally, dogs with keen olfactory senses are active as detection dogs in airports and police work, and research is being conducted to diagnose diseases based on the odors present in the breath of sick individuals. While it is challenging to develop technology that can match a dog's sense of smell for everyday use, we have developed a new two-dimensional electrochemical sensor and built a system that utilizes a large number of sensors simultaneously. Ordinary sensors increase sensitivity by enhancing their ability to capture odors, but we aim to achieve high-sensitivity electronic noses from a new perspective: even if a sensor captures an odor, it releases it so that the next sensor in line can capture it and produce a signal, repeating this process.
