Wearable Microneedle Sensors for Healthcare

Dear Colleagues,

The rapid development of wearable sensors provides cost-effective and portable measurement tools to improve or replace traditional laboratory diagnostic techniques. Among them, wearable sensors based on microneedles have attracted much more attention because of their minimally invasive characteristics and great potential in detecting various analytes. Traditional injection and analytical sampling commonly use metal needles, which not only easily bring pain and fear to patients, but also present a risk of infection at the site of insertion. The small size, painlessness, and portability of wearable microneedle-based sensors have shown promising application in both sampling and in situ detection, such as transdermal sampling, drug delivery, and physiological marker sensing. A common goal of wearable microneedle sensors is to protect and improve human health, whether through tissue fluid samples or direct health diagnosis. Representative examples include, but are not limited to, microneedles for transdermal sampling, wearable microneedle sensors for transdermal detection, wearable microneedles for transdermal drug delivery, and multifunctional wearable microneedle-based systems. Therefore, this Special Issue seeks to showcase articles and reviews that focus on the latest results and findings in wearable microneedle sensors and their applications in healthcare.

We look forward to receiving your submissions!

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 2100 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.
