Passive Wireless and Self-Powered Wireless Sensors and Systems

Dear Colleagues,

Passive Wireless sensors are a type of device that perform sensing and signal transmission when they are activated by external stimuli. Representative devices include piezoelectric resonators, LC resonators, surface acoustic wave resonators, etc. Self-Powered Wireless Sensors, on the other hand, are a class of devices and systems that can work without relying on an external power supply. They collect abundant waste energy from their surroundings, such as mechanical vibrations, walking, residual heat, microwave energy, etc. through electrostatic, piezoelectric, thermoelectric, triboelectric effects etc. These devices may provide either electrical signal output to form self-driven sensors or energy to form self-powered sensor systems. Passive Wireless and Self-Powered Wireless Sensors are the key components for state-of-art smart systems, and play an essential role in the modern information era, with widespread applications in intelligent manufacturing, smart homes and cities, smart medicine, etc. This Special Issue aims to provide an opportunity to address the aspects of simulation, design, materials, fabrication and applications of Passive Wireless and Self-Powered Wireless Sensor systems from both academic and industrial perspectives. Contributions that include novel sensor design, operation principles, energy collection, energy collection circuits and innovative sensors based on new concepts such as parity-time symmetry or coherent perfect absorption, etc., are particularly encouraged. Both review papers and original research articles are welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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.
