Special Issue Information

Dear Colleagues,

Energy harvesting consists of scavenging energy from the surrounding environment knowing that this energy would be “lost” if not scavenged. To scavenge small-scale kinetic energy, the use of a piezoelectric nanogenerator (PENG) is one of the most studied and developed approaches. It is based on the exploitation of the direct piezoelectric effect to transform the ambient kinetic energy—mostly vibrational—into electrical energy. Whilst the term PENG was initially introduced when referring to ZnO nanowires being used as materials to scavenge such small-scale energy, the word nowadays refers to piezoelectric energy harvesting more generally, whether standard materials (e.g., PZT, AlN) or novel materials (e.g., nanowires) are employed. Indeed, the driving mechanism of PENG is Maxwell’s displacement current. Potential applications of PENG are numerous as it allows self-powered and autonomous nano-, micro-, mini-, or meso-scaled devices, for example, implantable electronics in biomedical applications, geotracers and animal tracking devices, wearable devices, multifunctional shoes, tires monitoring sensors, autonomous sensors in automotives, building monitoring sensors, and self-powered vibration damping devices in structures. Nowadays, we are witnessing a variety of attractive approaches in the emerging research and development for increasingly more efficient PENGs with more diversified applications. This Special Issue aims to present a collection of articles, including review papers, that cover the recent research and development on PENG techniques as well as their applications. Collectively, the papers in this issue will address fundamental, technological, and application aspects.

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 1600 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.
