Special Issue Information

Dear Colleagues,

Nowadays, resonant sensors based on Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW)  devices are key components in several telecommunication systems and Internet of Things (IoT) applications. In particular, they are used in wireless sensor networks for environmental monitoring (where the sensitivity of their piezoelectric substrate materials are exploited for measurements of physical parameters such as temperature, stress, and strain), as high-performance band pass filters in wireless communication transceivers (with more than 3 billion SAW filters manufactured every year and used in radio receivers for mobile cell phones, base stations, and RF front ends), as low-cost and small-footprint chemical and biochemical sensors in industry, automotive, and health care applications (where they are employed, for instance, in the development of gas and VOCs sensors, by depositing nanostructured sensing materials on the electrodes) and, more recently, in advanced medical instruments based on microfluidics, where they are used to pump and drive liquids and for enabling high-precision control of the liquid flow. 

In all these contexts, signal processing techniques and machine learning algorithms can be used to improve performance and increase the number of applications of such as devices in real IoT scenarios.

The aim of this Special Issue is to publish high-quality research papers as well as review articles addressing recent advances ion IoT applications based on resonant devices and sensors and, at the same time, to provide an opportunity for researchers to publish their latest research and developments in this context, including design, modelling, characterization, and signal processing techniques for resonant devices.

In this work, a SAW resonator is characterized in terms of admittance (Y-) parameters in the temperature range spanning from 0 °C to 100 °C, with the aim of highlighting how its physical properties are affected by the temperature change. A lumped-element equivalent-circuit model is used to represent the device under test at the considered temperature conditions and a parameters extraction process based on a Lorentzian fitting is developed for the determination of the equivalent-circuit elements in the investigated temperature range. A very good agreement is observed between the performed measurements and the model simulations. The characterization process and the subsequent equivalent-circuit parameters extraction at different temperature values are described and discussed. Full article
