Wireless Power Wiki

Let's us look at the timeline of the number of papers (journal and conference papers) published on wireless power related topics. We limit ourselves to Scopus because we are not trying to do a rigorous study, we just want to get a general idea.

Methodology:

• Search on www.scopus.com
• Search within “All fields”
• Search documents containing: “wireless power” OR “wireless energy”

The strings “wireless power” OR “wireless energy” will obviously not capture every document on wireless power, but it's just to get an idea of the rise of publications. A staggering average annual growth of 29% papers per year can be seen in the last two decades! Indeed, wireless power transfer is on the rise!

Methodology:

• Search on www.scopus.com
• Search within “All fields”
• Search documents containing: “inductive wireless” OR “inductive charging” OR “inductive coupling” OR “inductive power”

Not surprisingly, most papers deal on inductive wireless power transfer. In the last two decades, an average annual growth of 18% papers per year can be seen. This might seem strange, since inductive WPT is already available on the market. But apparently, there is still a lot to be figured out! Those who think that inductive is not worth researching anymore, the numbers say otherwise!

Methodology:

• Search on www.scopus.com
• Search within “All fields”
• Search documents containing: “capacitive wireless” OR “capacitive charging” OR “capacitive coupling” OR “capacitive power”

Capacitive wireless power transfer is the little brother of inductive power transfer. O Last two decades: an average annual growth of 12% papers per year.

Methodology:

• Search on www.scopus.com
• Search within “All fields”
• Search documents containing: “a”.

Last two decades: an average annual growth of 6% papers per year.
