Special Issue Information

Dear Colleagues,

It has been over 60 years since Sauerbrey reported the principle of the quartz-crystal microbalance (QCM) method. QCM-based sensors are one of most widespread sensors in terms of convenience and reliability. For example, they can detect the thickness of deposited material, adsorbed gas molecules, humidity, and biomolecules. In recent years, the Internet of Things (IoT) has attracted attention. QCM-based sensors are expected to be a powerful tool for IoT.

This Special Issue is dedicated to the discussion of the state-of-art in QCM sensors, and to challenging applications not only for gas and bio-sensing but also for the primary industries such as agriculture, the aquatic products industry, and the livestock industry.  Micro and nanomaterials have been assembled in QCM sensors in the past decade. These challenging, materials-coated, QCM-based sensors are covered in this Special Issue.

Both review articles and original research papers are solicited. This Special Issue will benefit greatly from papers describing successful QCM-based sensors that have not been possible with other sensors such as optical sensors and electrochemical sensors.

Manuscript Submission Information

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 submissions that pass pre-check are 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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Lateral field excitation quartz crystal microbalance (LFE-QCM) can detect both the electrical properties (conductivity and permittivity) and mechanical properties (viscosity and density) of the liquid.

Lateral field excitation quartz crystal microbalance (LFE-QCM) can detect both the electrical properties (conductivity and permittivity) and mechanical properties (viscosity and density) of the liquid. In practical applications for detecting electrical properties, the viscosity and density of the liquid will also change. This research proposed a dual-channel LFE-QCM for reducing the influence of density and viscosity. The sensing layer of one resonant element is almost bare, and the other is covered by a metal film as a reference. Different organic solutions and NaCl solution were used to study the influence of mechanical properties and the temperature on electrical properties. The experimental results demonstrate that the dual-channel LFE-QCM is necessary for properly detecting electrical properties of the liquid. Full article
