Special Issue Information
Dear Colleagues,
With the rapid development of flexible electronics and micro–nano technologies, the demand for sustainable, independent, and maintenance-free sensor nodes has become increasingly urgent, especially in relation to the Internet of Things (IoT), wearable sensing systems, remote sensing, and smart environments. However, current power units represent one of the biggest limitations in wearable and portable sensor networks due to their frequent need for charging and replacement. As a result, self-powered sensor nodes (such as for pressure, temperature, light, or chemical composition) that do not require an external energy supply have become vital. Energy harvesters that convert ambient energy from various sources, such as piezoelectric and triboelectric harvesters for harvesting mechanical energy, thermoelectric harvesters for gathering thermal energy, and photovoltaic harvesters for gathering solar energy, have been widely investigated. Accordingly, this Special Issue will showcase research papers, short communications, and review articles that focus on (1) material and structural design, fabrication and miniaturization, and energy storage and management in energy harvesters and (2) circuit design, integration, sustainable systems, and applications in self-powered sensors.

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.
