Special Issue Information

Dear Colleagues,

This Special Issue is proposed to encourage further research and development of energy harvesters as mobile and remote power sources.

Development of energy harvesting devices should be carefully planned considering their target application. Powering wireless sensor nodes is one of the most attractive applications of energy harvesting technology for various monitoring purposes for large-scale structures and machines such as bridges, railroad, wind turbines, and naval platforms, as well as biosystems, such as the human body and/or animals. An energy harvester needs to be designed to meet the power requirements of the application (e.g. sensor), and integrated with a power management circuit for maximum power conversion and seamless sensor operation.

Original contributions including the state-of-the-art, point out the benefits of emerging technologies, experimental studies, or investigate the novel schemes and applications are welcome to submit. The topics of interest include, but are not limited to the following:

  • Integration of wireless sensor nodes with energy harvesters
  • Power management circuit and power storage
  • Battery science for minimum leakage
  • Novel energy harvesting concept to meet the power requirements of a specific application(s)

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. Electronics is an international peer-reviewed open access semimonthly 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 2400 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.

This paper studies the design scalability of a Γ-shaped piezoelectric energy harvester (ΓEH) using the generalized classical Ritz method (GCRM) and differential evolution algorithm. The generalized classical Ritz method (GCRM) is the advanced version of the classical Ritz method (CRM) that can handle a multibody system by assembling its equations of motion interconnected by the constraint equations. In this study, the GCRM is extended for analysis of the piezoelectric energy harvesters with material and/or orientation discontinuity between members. The electromechanical equations of motion are derived for the PE harvester using GCRM, and the accuracy of the numerical simulation is experimentally validated by comparing frequency response functions for voltage and power output. Then the GCRM is used in the power maximization design study that considers four different total masses—15 g, 30 g, 45 g, 60 g—to understand design scalability. The optimized ΓEH has the maximum normalized power density of 23.1 × 103 kg·s·m−3 which is the highest among the reviewed PE harvesters. We discuss how the design parameters need to be determined at different harvester scales. Full article
