Stretchable and Wearable Electronics

Dear Colleagues,

Stretchable and wearable electronics have emerged and received significant interest in both research and commerce in recent years. This interest stems from the huge demand for their unique electrical and mechanical performance, which can endow electronic devices unprecedented applications.

On the one hand, they can be used in circumstances where they were previously difficult to apply, for example, human skin, tissue-like electronics, stretchable supercapacitors and other circumstances, which greatly broadens the application scenarios for electronic devices. On the other hand, a large number of solution-processable organic or nano materials are adopted in them, and printing technology such as 3D printing, ink-jet printing and some other deposition methods, such as thermal evaporation, sputtering and chemical vapor deposition (CVD), alone or in combination, can also be used to fabricate them. These features make them significantly more available compared to traditional silicon-based electronics, making the manufacturing cost significantly lower and facilitating the diffusion of flexible electronics. As a result, they play an extremely important role in promoting the development of stretchable and wearable electronics. Furthermore, 5G technology and Internet of Things (IoT) technology are expected to contribute to dramatic changes in the fields of healthcare, environmental monitoring, human–machine interface, and energy conversion.

The aims of this Special Issue are to showcase the latest developments in stretchable and wearable electronics, which will cover, but are not limited to, the following categories:

• Flexible electronics;
• Textile-based electronic devices;
• Stretchable supercapacitors;
• Biological and chemical sensors;
• Organic thin-film transistors;
• Photovoltaic cells;
• Flexible logic circuits;
• Flexible photodetectors;
• Actuators;
• Hydrogels.

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. Electronics 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.
