Radio Frequency Energy Harvesting - Sources and Techniques

A prototype wave energy converter (WEC) was proposed, consisting of a heaving cylindrical buoy with an internal permanent magnet linear generator. A mathematical model of the prototype WEC is derived by coupling a hydrodynamic model for the motion of the buoy with a vibration energy harvester model for the generator. The wave energy resource is assessed, using established mathematical descriptions of ocean wave spectra and by analysing measured wave data from the coast of Queensland, resulting in characteristic wave spectra that are input to the mathematical model of the WEC. The parameters of the WEC system are optimised, to maximise the power output while minimising the pitch motion. A prototype thermal energy harvesting device is proposed, consisting of a thermoelectric device sandwiched between airside and waterside heat exchangers. A mathematical model is derived to assess the power output of the thermal energy harvester using different environmental datasets as input. A physical prototype is built and a number of experiments performed to assess its performance.

The multiband Cantor fractal antenna has been designed and implemented on a package of rectifying circuits using additive manufacturing (combination of 3D inkjet printing of plastic substrate and 2D metallic screen printing of silver paste) for the first time for RF energy harvesting application.

of an RF power harvesting circuit [Ph.D

Indoor and outdoor field tests of the RF energy harvester have been conducted in the IMPACT lab and the King Abdullah University of Science and Technology (KAUST) campus territory, and 252.4 mV of maximum output voltage is harvested.

Hence RF energy harvesting is one the most popular type of power harvesting.

Energy harvesting - For all : Institute of Physics

An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. Current appropriate topics include:

- Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.)
- Optical systems (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.)
- Electromagnetic theory
- Microwave and millimeter wave devices, circuits, and systems
- Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials)
- Integrated circuits (memory, logic, analog, RF, sensor)
- Power devices and circuits
- Micro- or nano-electromechanical systems
- Circuits and modules for storage
- Superconducting electronics
- Energy harvesting devices, circuits and modules
- Circuits and modules for electronic displays
- Circuits and modules for electronic instrumentation

IEICE is publishing following English journals. Carefully choose the most suitable journal for submitting your paper.

The scope of ELEX has mainly been focused on device and circuit technologies since was established in 2012. Topics included in the might currently be regarded as out of scope of ELEX.

Papers that merely discuss antennas are considered to be out of scope. Exceptions are specific antennas concerning circuit technologies; (ex.) phased array or active integrated antennas.

Papers that treat signal/image processing or software-oriented technologies without relevance to circuits or devices are regarded as out of scope.

Measurement results are strongly required for papers relating to analog- and RF-circuit and memory technologies.

Authors can submit a manuscript related to conference publications if more than 30% of the content is new material. When you submit a manuscript related to conference publications:
- List the original conference publications in the reference and cite them in the text appropriately.
- Clearly state and discuss the progress from the original conference publications.
- Attach the original conference publications at the end of your manuscript for review.
- Make sure of the copyright compliance of your manuscript. (See the following "Originality of manuscript" section on this page.)
