Dear Colleagues,

Paper, as a ubiquitous material in everyday life, has been reinvented into low-cost, flexible sensors and electronics for a variety of applications such as ‘smart’ packaging, consumer electronics, energy harvesting and storage, low-cost medical diagnostics, just to name a few. Paper possesses many features particularly suitable for developing sensors and electronics. For instance, paper is flexible, lightweight, compatible with various printing techniques, and foldable for forming three-dimensional structures that cannot be readily made from other substrates such as silicon and plastics; porous paper wicks fluids and can be patterned into fluidic channels and reservoirs for constructing fluid-containing devices, such as biosensors and flow batteries. To enable sensing and electronic functionalities on paper substrates, functional materials, such as conductive inks, organic molecules, and semiconductive nanostructures, have been integrated onto paper substrates through different strategies. Specific structural designs of the paper substrates also bring new properties and functionalities to the paper-based devices. In the past decade, significant efforts have been spent on the research and development of paper-based sensors and electronics, leading to enormous technological advances and many commercial successes. This Special Issue seeks to report the recent advances in paper-based sensors and electronics by publishing research articles, communications, reviews and opinion articles from talented researchers working in this exciting area. Original articles are solicited on the following topics, without being limited to: paper-based actuators and physical sensors, paper-based biosensors, paper-based electronics, new paper device fabrication techniques, architectural and structural designs of paper-based sensors, design and synthesis of new functional materials for use on paper-based devices, and novel applications of paper-based sensors and electronics.

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.
