Metasurfaces for sensing and medical diagnostics

Sensors and their applications have received attention in the last few years, mainly due to the high demand of devices able to make improvements in quality, performance and safety across many industrial sectors. The automotive and medical industries being outstanding examples. Different technologies have been used in this regard and have produced reliable devices and systems. Despite this, some crucial technical drawbacks, which limit performance and reliability, are still present: limited response control, bandwidth, and relatively large dimensions. Metasurfaces, engineered electromagnetic materials, can overcome and/or mitigate such issues. In this paper, devices based on metasurface technology for advanced sensing and medical diagnostic applications are manufactured and experimentally validated. First, their properties are designed in terms of electromagnetic parameters and structure physical dimensions. An additive manufacturing process will use the specifications to physically realize the sensors. They will then be experimentally tested in a variety of bio-medical applications. Metasurfaces pave a new way to realize sensors and use them for many practical applications beyond sensing and diagnostics.
