Micro Energy Harvesting Systems: From Devices to Self-Powered Applications

Dear Colleagues,

The rapid development of the Internet of Things, wearable electronic devices, edge computing, and intelligent sensing systems has exposed the shortcomings of traditional battery-powered architectures, including low energy density, high maintenance costs, and environmental concerns. Against this backdrop, micro energy harvesting technology has emerged as a transformative solution, capable of enabling autonomous operation by capturing energy from various ambient sources, such as mechanical vibration, light, temperature gradients, and radio frequency signals. Micro energy harvesting systems involve multiple disciplines and integrate innovations in functional materials, device architectures, multi-physics modeling, power management circuits, and application-driven system integration. Their application prospects have expanded into areas such as smart cities, intelligent transportation, structural health monitoring, and implantable biomedical devices.

This Special Issue focuses on the latest advances in micro energy harvesting technologies, spanning novel device architectures, power management, energy storage, and self-powered applications. We invite the submission of original research articles and comprehensive reviews that address challenges related to micro energy harvesting systems. Topics of interest include, but are not limited to, the following:

1. Kinetic energy harvesting;
2. Thermoelectric energy harvesting;
3. RF energy harvesting;
4. Photovoltaic energy harvesting;
5. Wearable energy harvesting;
6. Bio-inspired energy harvesting;
7. Modeling, simulation, and experimental characterization of energy harvesters;
8. Power management for energy harvesting systems;
9. Integrated energy storage for self-powered systems;
10. Self-powered integrated/embedded systems;
11. Real-world deployment and applications of energy harvesting systems.

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 250 words) can be sent to the Editorial Office for assessment.

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.
