    • Flexible metamaterials for wireless strain sensing 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Puttlitz, C.; Demir, Hilmi Volkan (American Institute of Physics, 2009-11-04)
      We proposed and demonstrated flexible metamaterial-based wireless strain sensors that include arrays of split ring resonators (SRRs) to telemetrically measure strain. For these metamaterial sensors, we showed that a flexible ...
    • Flexible strain sensors based on electrostatically actuated graphene flakes 

      Fardindoost, S.; Alipour, A.; Mohammadi, S.; Gökyar, S.; Sarvari, R.; Iraji Zad, A.; Demir, Hilmi Volkan (Institute of Physics Publishing, 2015)
      In this paper we present flexible strain sensors made of graphene flakes fabricated, characterized, and analyzed for the electrical actuation and readout of their mechanical vibratory response in strain-sensing applications. ...
    • Metamaterial based telemetric strain sensing in different materials 

      Melik, R.; Unal, E.; Perkgoz, N.K.; Puttlitz, C.; Demir, Hilmi Volkan (Optical Society of American (OSA), 2010)
      We present telemetric sensing of surface strains on different industrial materials using split-ring-resonator based metamaterials. For wireless strain sensing, we utilize metamaterial array architectures for high sensitivity ...
    • Nested metamaterials for wireless strain sensing 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Santoni, B.; Kamstock, D.; Puttlitz, C.; Demir, Hilmi Volkan (IEEE, 2009-12-28)
      We designed, fabricated, and characterized metamaterial-based RF-microelectromechanical system (RF-MEMS) strain sensors that incorporate multiple split ring resonators (SRRs) in a compact nested architecture to measure ...
    • Wireless thin-film microwave resonators for sensing and marking 

      Alipour, Akbar (Bilkent University, 2017-06)
      Rapid progress in wireless microwave technology has attracted increasing interest for high-performance wireless devices. The thin- lm microwave technology is now evolving into the mainstream of applications but signi ...
