This.
I don't know how wide / thin the copper traces can be but I can't imagine them not being the dominant mass on that surface.
Then, who cares if the membrane is 1, 50 or 500 nm.
Also, I just love the wording on the website to avoid being caught blatantly lying

So, I don't know if you guys watched the video about Dr. Fang on Tyll's website with the links to the sunday planar panel monologue?
As was pointed by someone on head-fi, it would appear the conductive traces can be deposited on the diaphragm and their thickness is in the same order as the diaphragm itself.
The other interesting bit was Fang's comment that all he had to care for in terms of motor design was to keep a low surface mass density on the diaphragm / trace assembly such that the inertial forces are small compared to the emag force.
I still think Tyll was right questioning the behavior of the diaphragm in those regions where there are no traces, the thing must be wabbling all over the surface but the point was not addressed.
Last surprising point for me was Fang's apparent lack of understanding of the resistive & (lack of) reactive impedance an ortho driver presents as a load to an amplifier (maybe some language barrier issue but he seems quite fluent in English). The fellow in the audience who asked the question seemed, uh..., taken apart by Fang's candid response on relying on his electrical engineers for this bit
.
Anyhow, am still quite interested to hear the HE1000, this usage of thin diaphragm + conductive trace deposition seems like a good idea. Isn't that the first of the kind in the world of planar headphones?
