Surfaces of natural and synthetic materials can have different colors, can reflect or absorb radio waves, can be hot or cold, can feel solid or soft when we touch them. It appears that the choice is wide, but our developing society needs new technologies which require materials with specific, application-defined properties. Moreover, future robots and other machines serving the digitalized society will need sensing and adaptive “artificial skins”, which will work as intelligent interfaces between humans, machines, and the environment. In this talk we will review recent advances in the design and realization of electromagnetic and acoustic metasurfaces: artificial skins with desired electromagnetic and acoustical responses. Furthermore, we will discuss possibilities of making such artificial skins sensible, tuneable, and adaptable to the environment. Merging electromagnetic and acoustic functionalities with programmable artificial intelligence of embedded microprocessors can potentially open up a route towards creation of artificial intelligent skins.
Professor Sergei A. Tretyakov (Fellow, IEEE) received the Dipl. Engineer-Physicist, the Candidate of Sciences (PhD), and the Doctor of Sciences degrees (all in radiophysics) from the St. Petersburg State Technical University (Russia), in 1980, 1987, and 1995, respectively. From 1980 to 2000 he was with the Radiophysics Department of the St. Petersburg State Technical University. From the year 2000 he has been working in Helsinki University of Technology (Finland), which became Aalto University in 2010, after a merge with two other universities in Helsinki. Presently, he is professor at the Department of Electronics and Nanoengineering, Aalto University, Finland. The main scientific interests of prof. S. Tretyakov are electromagnetic field theory, complex media electromagnetics, artificial electromagnetic materials and surfaces, antennas, and microwave engineering. He is the author or co-author of five research monographs, 16 book chapters, and more than 270 journal papers. More information can be found on the web sites users.aalto.fi/sergei and meta.aalto.fi.
