Special Issue Information

Dear Colleagues,

We are seeing a growing interest in the potential of advanced MEMS resonators and sensors in various fields, including healthcare, communication, environmental monitoring, energy harvesting, automotive, industrial, consumer electronics, aerospace, and defense, thanks to their extraordinary sensing capabilities and advantages in terms of size, power, cost, and reliability.

This Special Issue aims to bring together recent progress regarding advanced MEMS resonators and sensors. It will focus on various aspects of MEMS resonators and sensors, including materials, designs, and applications. Topics of interest include, but are not limited to:

  • Novel materials for MEMS resonators and sensors, such as 2D materials, piezoelectric materials, and soft materials;
  • Innovative designs and fabrication techniques for MEMS resonators and sensors, such as machine learning, biomimicry, and digital fabrication;
  • Advanced applications of MEMS resonators and sensors, such as in communication, healthcare, environmental monitoring, and energy harvesting;
  • Theoretical and experimental studies on the dynamics, stability, and reliability of MEMS resonators and sensors;
  • Integration of MEMS resonators and sensors with other micro- and nanosystems, such as electronics, photonics, and fluidics.

In this paper, the study is supported by design, FEA simulation, and practical RF measurements on fabricated single-port-cavity-based acoustic resonator for gas sensing applications. In the FEA simulation, frequency domain analysis was performed to enhance the performance of the acoustic resonator. The structural and surface morphologies of the deposited ZnO as a piezoelectric layer have been studied using XRD and AFM. The XRD pattern of deposited bulk ZnO film indicates the perfect single crystalline nature of the film with dominant phase (002) at 2θ = 34.58°. The AFM micrograph indicates that deposited piezoelectric film has a very smooth surface and small grain size. In the fabrication process, use of bulk micro machined oxide (SiO2) for the production of a thin membrane as a support layer is adopted. A vector network analyzer (Model MS2028C, Anritsu) was used to measure the radio frequency response of the resonators from 1 GHz to 2.5 GHz. As a result, we have successfully fabricated an acoustic resonator operating at 1.84 GHz with a quality factor Q of 214 and an effective electromechanical coupling coefficient of 10.57%. Full article

Triangular resonators re-shaped into Sierpinski geometry and U-shaped resonators were designed, linking them with single-pole-double-through (SPDT) RF MEMS switches to provide frequency tuning for potential applications in the K-Band. Prototypes of band-stop narrowband filters working around 20 GHz and 26 GHz, interesting for RADAR and satellite communications, were studied in a coplanar waveguide (CPW) configuration, and the tuning was obtained by switching between two paths of the devices loaded with different resonators. As a result, dual-band operation or fine-tuning could be obtained depending on the choice of the resonator, acting as a building block. The studied filters belong to the more general group of devices inspired by a metamaterial design. Full article
