Battery-free Smart Sensors

Dear Colleagues,

Smart phones and tablet PCs are now seen as modern essentials around the world. These electronic devices have many individual sensors or software for different services, such as finger print recognition, face recognition, health monitoring systems, and so on in the one device. It is well known that video systems are providing local security in large cities around the world.

Many monitoring systems specialists anticipate that we will need to have hundreds of sensors per person in public spaces. This suggests that energy consumption around the world will be unacceptably large—all existing and indeed predicted power sources in the world cannot provide the energy demanded by these sensor systems.

This difficulty is already being publicized by some scientists, by statements in several international conferences that we need battery-free sensor systems worldwide.

This Special Issue discusses possible solutions to achieve future battery-free sensor systems. Therefore, the scope of this Special Issue solicits papers discussing the following topics:

• Device technologies for low-energy applications;
• Circuit technologies for low-energy applications;
• Solar-battery devices with high efficiency, and other devices for energy generation based on organic materials, and so on;
• Functional materials and devices for specific sensor applications, such as health monitoring, air pollution monitoring, traffic monitoring, and so on;
• Sensor-related technologies.

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. Sensors 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 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.
