Special Issue Information

Dear Colleagues,

Structural Health Monitoring (SHM) involves a process of in-service damage identification and health assessment for a structure through an automated monitoring system. To ensure a reliable operation and to schedule maintenance and repair work in a cost‐effective manner, it is necessary to continuously monitor and assess the structural performance and to have an accurate estimation of the remaining useful life. SHM requires intensity studies in various fields due to its multi-disciplinary nature, including sensing network, data acquisition, signal processing, damage assessment and decision making.

The special issue focuses on the sensing technology in particular for the wireless sensors. In SHM, various types of sensors are often adopted for measuring different types of quantities, such as mechanical (e.g. strain, displacement, crack growth, stress and pressure), environmental (e.g. temperature and humidity), and chemical (e.g. corrosion, carbonation, pH and oxidation). The most common sensors include piezoelectric (PZT) sensors, optical fiber sensors, accelerometers, strain gauge. The quality of sensors should not be altered by environmental effects such as temperature, humidity and electromagnetic fields.

Wireless sensors are gaining popularity for monitoring of engineering structures because they are inexpensive and easy to install. The use of wireless communication has been investigated for the transfer of data between sensors and the data storage. Such wireless monitoring systems are assembled from low‐cost wireless sensors that offer sensing, communication and computing in a single device. Wireless sensors are generally divided into two groups: passive sensors and active sensors. Passive sensors measure a specific physical or chemical quantity by responding passively to the state of the system to be monitored. Active sensors, by contrast, generate signals in a controlled manner, and then they sense the response of the system to those signals. Compared to tethered sensors, wireless sensors have several advantages including limited demands for connecting hardware, capability for higher number of sensors and power sources via innovative methods. Without wires, wireless sensors require internally stored power for operation. Several power sources can be used in wireless sensing systems, such as conventional batteries, radio frequency identification (RFID), ambient energy sources, such as solar, vibration and thermal.

Articles reporting recent advances in sensor materials, sensor properties, sensor device concepts, sensor fabrication and testing techniques, application-oriented sensor systems, as well as closely-related topics, are welcome. This Issue will accept high-quality articles containing original research results, and review articles, which are relative to Structural Health Monitoring.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 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.
