The field of metamaterials and artificial materials has rapidly grown in the last decade, spanning microwave, THz and optical frequencies, with a wide range of applications. One of the most intriguing possibility offered by metamaterials is the large flexibility in their dispersion engineering properties, which may provide novel tools to significantly enhance the sensitivity of practical devices. In this context, concepts like electromagnetically induced transparency, extremely slow waves, large field enhancements, and ultracompact resonances have been successfully established in a variety of metamaterial geometries and setups, providing resonance Q factors and robustness to absorption and disorder superior to those in natural materials. These anomalous features may pave the way to a large set of exciting possibilities to dramatically improve current sensing devices, with applications in biology, medicine, chemistry and other related fields. This special issue of Sensors is specifically devoted to the application of novel metamaterial concepts and geometries for sensing devices with improved sensitivity and resolution.
