Design and Optimization of Energy Harvesting Systems in Electronics

Dear Colleagues, 

Ultra-low power consumption, energy harvesting, and wireless connectivity are technologies that enable the creation of smart devices in which new functions can be integrated, like active safety enhancement, remote diagnostics, and real-time condition monitoring to predict faults and prevent costly operation breakdowns. These functions are rapidly gaining interest in many fields of application, like the Internet of Things (IoT), Industrial Internet of Things (IIoT), smart farming, Industry 4.0, and automotives.
On one hand, wireless connectivity has allowed for the creation of miniaturized devices able to work in harsh environments and that can be placed in locations not accessible with traditional solutions. On the other hand, wireless devices are usually battery powered and their miniaturization necessitates using smaller energy storage devices that can significantly limit the device’s lifetime, and consequently lead to an unacceptable battery replacement rate for the most applications.
To overcome this limitation, both industry and academia are working towards the creation of energy-neutral devices, concentrating efforts on both reducing the power consumption and developing systems able to gather the needed energy directly from the environment where they operate.

In this Special Issue, topics can include, but are not limited to, the following:

• Advancements in energy-aware design techniques and energy harvesting solutions.
• Simulation tools and modeling of energy harvesting systems.
• Design methodologies of energy harvesting systems.
• Real applications of self-powered devices.
• Ultra-low-power hardware architectures for energy-constrained devices.
• High-efficiency energy harvesting circuits.
• Context-aware power management circuits for energy-neutral devices.
• Ultra-low-power front-end electronics.
• Ultra-low-power communication interfaces.
• Smart wake-up and self-startup circuits for self-powered devices.
• Smart energy storage circuits or 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 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.
