Special Issue Information
Dear Colleagues,
Optical fiber-based pressure sensors have emerged as a promising technology, ushering in a revolution in the field of pressure measurement. In recent years, these sensors have showcased remarkable accuracy, sensitivity, and versatility. They possess several advantages, including immunity to electromagnetic interference and the capability to function in challenging environments. Nevertheless, there are still some challenges, such as the need for heightened sensitivity, miniaturization, and cost-effectiveness. Researchers are actively tackling these challenges by exploring innovative materials and fabrication techniques. On one front, it is feasible to elevate the performance of Fabry–Perot pressure sensor substrates or pressure-sensitive structures through the exploration of novel materials like crystals, ceramics, and alloy metals. On the other hand, delving into new Fabry–Perot structure fabrication processes, such as Micro-Electro-Mechanical Systems (MEMS), laser engraving, 3D printing technology, and others, offers the potential to enhance the stability and uniformity of sensor structures, thereby improving key performance parameters such as accuracy, repeatability, and linearity. In summary, the integration of optical fiber sensors with technologies from other fields is poised to drive groundbreaking advancements in pressure sensing and monitoring systems.

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.
