Piezoelectric Energy Harvesting Sensors and Their Applications

Dear Colleagues,

Piezoelectric sensors and actuators have been widely used due to their significant advantages. Recent trends are moving towards energy harvesting, self-powered sensors, miniaturization, 3D printing for fabrication, IoT sensor networks, and artificial-intelligence-based data analytics. In civil engineering applications, severe service environments and rough installation processes require packaging ruggedness, waterproofness, and superior stability of the sensors. Such challenging requirements have resulted in tough demands for improved design and fabrications. In addition, the monitoring of large civil infrastructure often requires sensor networks that consume significant quantities of energy. Self-powering and the use of locally harvested energy represent desirable features, especially in remote areas. In addition, long-term monitoring requires wireless data transmission and analytics of large-volume data. In this context, data analytics becomes a bottleneck. AI-based approaches such as machine learning and deep learning are promising to address this. This Special Issue will reflect recent developments in these trends.

Specifically, this Special Issue will cover the following areas: 1) innovative sensor design and fabrication; 2) optimal design and deployment of wireless sensor networks; 3) AI-based data analytics; and 4) integrated applications in safety and security assessments of civil infrastructures.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
