Special Issue Information
Dear Colleagues,
With the rapid advancement of the Internet of Things (IoT), wearable devices, and edge computing, conventional battery-powered systems are increasingly constrained by limitations such as low energy density, high replacement costs, and environmental pollution. Against this backdrop, self-powered sensing systems based on micro-energy harvesting from ambient sources (e.g., vibration, light, heat, and radiofrequency signals) have emerged as a transformative research frontier. This field, driven by synergistic advancements in micro/nano-fabrication technologies, novel functional materials (including triboelectric nanogenerators, piezoelectric/thermoelectric materials, and photovoltaic semiconductors), and ultra-low-power electronics, is progressively enabling closed-loop architectures that capture dispersed environmental energy to autonomously operate smart terminals. Self-powered systems are expected to evolve toward intelligent, miniaturized, and highly environment-symbiotic paradigms. By leveraging cross-scale co-innovation across materials, devices, and systems, scenario-specific self-powered solutions will be developed to propel sensing systems from a “passively powered” mode to an “environment-symbiotic” ecosystem.
This Special Issue aims to showcase the latest micro-energy harvesting technologies and self-powered sensing system applications from the perspectives of mechanisms, materials, fabrication, and applications, encompassing research papers, short communications, and review articles. The range of the topics may include, but need not be limited to, the following aspects: piezoelectric, triboelectric, photovoltaic, thermoelectric harvesters, self-powered sensors, multifunctional hydrogel, and flexible wearable devices.

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.
