Position Sensor

Dear Colleagues,

Measurements of physical displacement, position, and dimensions of objects are required in many technical applications such as precision manufacturing, scanning probe microscopy, profilometry, lithography, and robotics. The target distance in position sensing tasks can vary from the kilometer scale in LiDAR applications to nanometer scales in molecular and atomic manipulation tasks. Depending on the situation, the sensing accuracy can be compromised by numerous undesirable factors such as noise, crosstalk, nonlinearities, and target material properties. Other physical factors, such as limited power and space, atmospheric pressure, and temperature, also affect the adopted sensing material, fabrications procedure, and readout electronics. Hence, measurement and sensing of displacement and position is a continuously growing research field in the sensor industry and academia. However, recent survey publications focused on this field are limited and the variety of research fields related to sensing technology is considerably vast.

To facilitate rapid and effective advance of research in this field, Sensors aims to rapidly publish recent advances in the field of position and displacement sensors in a Topical Collection. We invite submissions bringing novelty or improvement in this field and addressing any aspect such as sensing materials, fabrication methods, sensing approaches, signal conditioning, speed of response, accuracy, resolution, and linearity. We are also interested in new applications and challenges in this field such as wearable sensors, proximity sensors, wrapage and flatness sensors, height or step height sensors, bed levelling sensors, and displacement sensors in positioning platforms, stages, scanning probes, and micromanipulation devices.

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.
