Cerious Technologies NEW Graphene Cables

Here is an excerpt from Boston Globe:
"...Novak Djokovic, who says the racquet will "give [his] game even more speed and control." Though whether or not that’s directly due to the graphene is anyone’s guess. ..."

More speed and control sounds perfect for driving my speakers!

Rob is right, he explains how it is being used. Most manufacturers remain vague. Again an excerpt from the Globe (different article):
"..The race is on to see which companies, in which industries, focus more on marketing the word GRAPHENE, and which focus more on using the material to make substantially better products. .."

PS from Graphene Tracker online,

HEAD’s new series of graphene-reinforced rackets are being promoted by the likes of Novak Djokovic and Maria Sharapova, with users reporting increased precision and ease of use, accompanied by decreased racket weight. In one of the early promotional videos, Novak’s new racket is called his “secret weapon”. The composition of the racket and the role of graphene was indeed secret, until the publishing of the graphene racket patent application.

HEAD chose to try and protect not only the use of graphene in rackets, but also in all other sporting goods, including skis, snowboards, golf clubs, and footwear. If the patent is approved with all its claims, it is sure to rake in large profits for HEAD, as other sporting goods manufacturers will certainly follow up with their own explorations of graphene. Strangely though, the patent application does not put a claim on balls made of graphene.

US patent application number 20130090193 describes the use of graphene as a reinforcing element in the build of a tennis racket. The graphene is embedded into an epoxy matrix, which makes at least a part of the racket’s structure. The use of graphene increases the racket’s performance, making it lighter in weight yet more durable than rackets used to date. The graphene also makes the racket’s stiffness along different directions more proportional, addressing a problem commonly experienced with non-graphene reinforced fibers. This means that tennis players will now have more freedom to throw their racket against the ground upon losing a point, knowing that graphene is there to help the racket survive and be used again.

Sorry to steer this away from audio. I "Know" about this area because I have worked as a consultant to both the golf (shafts) and tennis industries designing materials for them. Adding Graphene to the Epoxy mix versus ceramic micro-spheres will add little to the characteristics of rackets or golf shafts (BTW I was a regional champion tennis player and am still a solid 4.5 player nearing 60). This is marketing pure and simple. Since we came out with products that contain Graphene, I wish you could see all the Institutes, Trade Associations, and University Grant proposals we get looking for money. Graphene will be a $20 Billion dollar "industry" this year. Again I am sorry to have added to the steering of subject away from audio (which I LOVE) to technical aspects of materials which is work for me and just plain tedious! If you wish more information on materials write me at my website and I will be glad to elaborate without taking up space on the audio forum...

I play tennis evey day and have now about thirty rackets, ranging from Slazenger and Dunlop Muliply wood jobs, the Dunlop Max 200G, various vintage and newer Wilson, Head, Prince, graphite, carbon fiber, tungsten, magnesium, and others. I even have a Megaton Pro super widebody and Rex Professional super widebidy from Germany. To claim that the material in rackets is pure marketing is a little bit silly IMHO since each type of racket obviously has it’s own action, physical characteristics and feel, which are attributable to several factors including materials as well as geometry, strings, tension of strings, etc. Besides, why would a company like Head take out a patent on the Graphene racket technology? Doesn’t make sense. Is that itself a marketing ploy, taking out a patent?

Furthermore, and more to the point, why would Djokovich comment, regarding his Head Graphene tennis racket, "It’s my secret weapon." I suppose now I’ll have to check out the French Open today at 12 and see how Djokovich is doing with that heavily marketed Head Graphene racket. ;-)

Doncha agree tennis is a lot like audio - it’s a question of tweaking, materials, what strings to use, tension, vibration dampers, materials. ;-) especially what I do a lot of professionally, vibration isolation and resonance control, in terms of physics of materials.

I return you to your regularly scheduled programming.

Djokovich will be out on the court in the French Open in about 10 minutes at 1:15 EDT as Tsonga retired in match preceding him. One imagines he'll be playing with the Head Graphene racket. I suspect the powers that be at Head are on pins and needles. Let's see what that Graphene is all about. Heh heh
