Mobile Robot Olfaction

Male moths follow sexual pheromone over long distances to find their mates. Aquatic animals, e.g., crabs and crayfish, can track smell of food to survive in the dark ocean or at the bottom of lakes. The current research efforts in our group are focused on the development of robotic olfactory sensing systems that can detect odor plumes and track them down to their sources. The potential applications include searches for gas leaks, fire origins and hazardous chemicals. Our terrestrial robot can autonomously find a gas source placed in an indoor environment. Our crayfish robot mimics olfactory search behavior of crayfish, and searches for chemical sources underwater. Olfactory display devices are also being developed in our group to present “movies with scents” in virtual reality systems.

Explore nanoworld by light!

We are studying and exploring the great frontier of nanoworld by using light.
However, due to the nature of light so-called diffraction limit, conventional optical systems are useless to study nanoscale objects smaller than the wavelength of light. We have broken down this limit by using optical near-field, which is the strongly confined light field in the vicinity of a probing nanostructure.

Development of nano-optical systems

Based on recent advancements of nanofabrication technologies, plasmon resonance has attracted much interest. This phenomenon has been applied to biosensors, highly efficient solar power converters, nanooptical components and so on. Recently, this research field is called as "Plasmonics", and has been broadened among the world.
We have been focused on the relationship between plasmon resonance and electron field emission. We found so-called "Plasmon assisted field emission", which is expected as a novel photocathode. We are pursuing this principle in depth and applying it to the novel massively-parallel optically-controlled filed emitter arrays.
