Advances in Electronic Circuits for Energy Harvesting Based Wireless Sensor Networks

Dear Colleagues,

Wireless sensor networks (WSNs) are an effective, sustainable, and cheap solution for monitoring purposes of transportation vehicles, industrial implants, the environment, and smart cities. WSN devices are frequently employed in environments or infrastructures where a wired energy supply is not present or its distribution is not economically convenient. As disposable batteries are characterized by high maintenance costs, high environmental impact, and low reliability, energy harvesters (EHs), which are able to convert otherwise wasted forms of energy into electricity, are an effective solution for energy supply. However, the use of EHs is strongly limited by the low electrical power that they are able to generate. Therefore, the energy challenge emerges as one of the most critical issues in WSN design. As every sensor node requires power for data collection, processing, and communication, designing WSNs requires the optimization of efficiency from both the supply and the consumption points of view. With reference to supply efficiency, it is required to optimize both energy harvesting devices and the electronic interface placed between the energy harvester and the load, for maximum power point tracking (MPPT) purposes. With reference to consumption efficiency, it is required to optimize sensor node electronics, as well as network configuration, organization, and routing.

The topics of interest for publication include but are not limited to:

• Electronic circuits for wireless sensor networks;
• Low Power transceivers for wireless sensor networks;
• Electronic interfaces for energy harvesters;
• Maximum power point tracking;
• Energy harvesters (photovoltaic, piezoelectric, electromagnetic, etc.);
• Energy harvesting for the Internet of Things;
• Electronic interfaces for low-power sensors;
• Self-powered sensor systems;
• Low-power sensor networks;
• Wireless sensor networks powered by energy harvesting;
• Low-power communications.

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. Applied Sciences 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.
