Special Issue Information
Dear Colleagues,
The development of the IoT (Internet of Things) provides a unique development opportunity for the application of WSNs (wireless sensor networks). To realize power independence, sensor nodes are required to harvest energy from an ambient environment. Piezoelectric harvesters, scavenging energy from ambient vibration, have drawn a remarkable amount of interest in the energy-harvesting field over the past few decades due to their advantages of high-power density, low cost. and small scale. Therefore, piezoelectric energy harvesters are regarded as one of the most promising research areas for self-powering solutions.
Improvements on piezoelectric generators can be focused on two aspects: mechanical structure to increase power density or operation bandwidth and electronic interface circuits to enhance harvesting efficiency. This Special Issue is aimed at showcasing innovative strategies and progress in piezoelectric energy harvesting, encompassing research papers, short communications, and review articles. The range of the topics may include but need not be limited to the following aspects: 1) novel designs for piezoelectric harvesters, 2) new adjustable strategies for the structure and circuits of piezoelectric harvesters, 3) creative topology of interface circuits, 4) novel control strategies of interface circuits, 5) realization of self-powered interface circuits, and 6) modeling and dynamics of piezoelectric harvesters.

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 2600 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.
