Resonators based on bulk acoustic waves with a longitudinal or lateral exciting electric field and one- or two-port resonators on surface or plate acoustic waves will be considered. A gas-sensitive element uses a layer deposited on the surface of a piezoelectric resonator of any type, the mechanical or electrical properties of which change in the presence of the analyzed gas. Liquid sensors are developed by using the contact of the analyzed liquid with a resonator such as those considered, the main parameters of which change when the mechanical or electrical properties of the contacting liquid change. As for biological sensors, two variants are contemplated. In the first variant, an active layer containing immobilized antibodies, bacteria or a virus is applied to the surface of the resonator. When a specific reagent is added to this layer, its properties change, which allows the detection and identification of the bacteria or virus. In the second variant, the biological reaction occurs directly in a liquid suspension containing the studied microorganisms to which a specific or non-specific reagent is added. Changing the physical properties of the suspension will allow one to detect and identify microorganisms contained in the suspension.
This Special Issue aims to receive submissions of both review and original research articles related to biological, liquid and gas sensors including various types of piezoelectric resonators based on bulk, surface and plate acoustic waves. Such sensors are widely used to diagnose various diseases at an early stage, to monitor the environment and to control various liquids in the food and chemical industries. These sensors include:
- biological sensors for detection and identification of microorganisms, operating with active layers containing immobilized antibodies or bacteria or without them directly in liquid phase;
- liquid sensors for measuring the mechanical and electrical properties of the liquid in contact with the resonator;
- gas sensors for detection of the analyzed gas, including a gas-sensitive layer in contact with the resonator.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
