Special Issue Information

Dear Colleagues,

We are pleased to announce the Special Issue entitled “Feature Papers of Micromachines in ‘Engineering and Technology’ 2024”. In recent years, we have cooperated with many excellent scholars/scientific groups and published several very important high-level works that have already received numerous citations according to Web of Science data. We aim to introduce new insights into the scientific developments and cutting-edge technology related to micromachines in the engineering and technology fields, which will make a great contribution to the community.

This Special Issue will be a collection of high-quality papers by outstanding scholars from around the world. Both original research articles and comprehensive review papers are welcome. The papers will be published with full open access after peer review to benefit both authors and readers.

You are welcome to send short proposals for the submission of Feature Papers to our Editorial Office ([email protected]) before submission. These will undergo a preliminary evaluation by our Editors. Please note that selected full papers will still be subject to thorough and rigorous peer review.

We look forward to receiving your excellent work.

Prof. Dr. Stephen Edward Saddow
Guest Editor

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. Micromachines is an international peer-reviewed open access monthly 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

Virtual reality technology brings a new experience to human-computer interaction, while wearable force feedback devices can enhance the immersion of users in interaction. This paper proposes a wearable fingertip force feedback device that uses a tendon drive mechanism, with the aim of simulating the stiffness characteristics of objects within virtual scenes. The device adjusts the rotation angle of the torsion spring through a DC motor, and then uses a wire to convert the torque into a feedback force at the user’s index fingertips, with an output force of up to 4 N and a force change rate of up to 10 N/s. This paper introduces the mechanical structure and design process of the force feedback device, and conducts a mechanical analysis of the device to select the appropriate components. Physical and psychological experiments are conducted to comprehensively evaluate the device’s performance in conveying object stiffness information. The results show that the device can simulate different stiffness characteristics of objects, and users can distinguish objects with different stiffness characteristics well when wearing the force feedback device and interacting with the three-dimensional virtual environments.
