Dear Colleagues,

Wireless microdevices are getting smaller and smaller, to the point where such devices may flow in our blood stream, navigate inside blood vessels, digestive system, or inside our eyes. They may even transport cells or treatment to a specific target. However, despite massive advances in integration, the most recent microbots lack a full integration of the desired feature sets. Locomotion at micro/nanoscale is a current challenge; remote manipulation, such as triggering a drug delivery device or triggering and controlling a biopsy, is another open challenge; powering and communication with small devices is also an issue, since power sources and wireless links degrade significantly with miniaturization.

The fabrication of 3D devices integrating RF chips, flexible material integration with silicon, and self-assembling technologies may allow unprecedented level of integration and miniaturization of biomedical devices. However, we need new assembling technologies, new low-power devices, new integration technologies, and new efficient wireless power and communication solutions. With this Special Issue, we intend to highlight enabling technologies that will contribute to the development of smaller and smarter wireless microdevices that will make the difference in biomedical applications.

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 papers will be 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 1000 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.
