Special Issue Information

Dear Colleagues,

This Special Issue is devoted to introducing new theories, new methods, new technologies, and their applications in the field of advanced ultrasonic motors and sensors. The ultrasonic motor is a micro motor developed in the past 40 years, and it has small size, light weight, no electromagnetic interference, shape diversification, and other unique advantages. It also has a wide range of applications in space satellite drive mechanisms, high-end medical equipment, optics, robotics, micro terminal equipment, and other fields. In addition, ultrasonic sensors have been widely used, in recent years, in the fields of robotics, minimally invasive surgery (MIS), health monitoring, human–computer interaction, smart prosthetics, bionics, energy harvesting, and surface detection. In addition, application fields are constantly expanding.

In the current era, as there are more in-depth applications for ultrasonic motors and sensors, there are more scientific and engineering problems, requiring researchers to invest a lot of energy and time into exploring and solving them. They also lay a solid foundation for future large-scale applications of ultrasonic motors and sensors. We welcome contributions on topics such as the structural design and optimization of ultrasonic motors and sensors, drive and control, complex environment adaptability, and application case studies.

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. Applied Sciences 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 2400 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.

Outdoor solutions aiding the navigation of visually impaired individuals can seamlessly transition to indoor environments. Take, for instance, the adaptation of special lanes and configurations on the floor. However, these existing solutions fall short when it comes to addressing obstacles above ground level, such as open windows, as highlighted in a previous article on the use of ultrasonic glove for visually impaired users. In response, the present proposal is a user-friendly, cost-effective solution that is capable of detecting elevated obstacles. Importantly, this solution aligns with a user’s language preferences, eliminating the need for learning new languages or possessing IT skills. Users simply specify their desired language for the prototype to communicate in, ensuring a personalized experience. The system alerts users to the presence of obstacles through varying levels of warning, calculated based on the distance between the obstacle and the user’s current position. This approach not only enhances safety but also prioritizes accessibility and ease of use. Full article
