Apple wants to use graphene membranes to enhance next-gen iPhone speakers or microphones

Apple was granted a new patent (filed in 2015) that details an audio device that uses a diaphragm made from a graphene-enhanced composite material. Apple's graphene membrane can be used in a speaker, microphone or headphone device. The patent specifically includes an image of an iPhone device as an example application.

Apple explains that as devices become smaller and lighter, it is ever more challenging to provide high quality audio using conventional materials - and graphene may improve the mechanical response of the audio device. In addition, in some cases, the use of graphene or graphene flake materials may reduce or eliminate the need for additional external damping.

Graphene 3D lab files patent for a 3D printer that can print a graphene-based OLED

Graphene 3D Lab has announced filing a provisional patent for a process of 3D printing an OLED light source that immediately functions when printed, with a graphene coated transparent conductor window. This unique structure is the product of an innovative multi-functional 3D Printer, which can make thin films as well as 3D structures.

The printer patent relates to a technology that should lead the industry in multiple deposition techniques, robotic manipulator, laser and UV curing capabilities. G3L considers the new IP a dramatic leap forward, offering the ability to 3D print with multiple functional materials at the same time, including the ability to 3D print a working light. This printer was reportedly designed to maximize the attributes of the functional materials that the company already developed, and plans to introduce in the future to the market.

Haydale HDPlas® process granted European patent for wide range of nanoparticles

Haydale announces that it has received confirmation from the European Patent Office (EPO) of the decision to grant a European Patent for its proprietary HDPlas® functionalization process for graphene and other nanoparticulate materials.

The European Patent is the key process patent underlying the Company's proprietary functionalization treatment and is one of a number arising from the families of patent applications surrounding Haydale's unique plasma functionalization process. Haydale already has a granted patent in China and has visibility on the patent application in Australia, which is expected to proceed to grant within the next 3-4 months.

Graphene 3D Lab files patent for graphene manufacturing

Graphene 3D Lab has filed a non-provisional patent relating to the preparation and separation of atomic layers of graphene. This technology is said to represent a new, energy-efficient process to manufacture, sort and classify graphene nanoparticles, resulting in the potential for large-scale production of high-grade graphene.

The patent is relevant to graphene nanoplatelets - it covers a new, energy-efficient, non-chemically invasive process that significantly lowers the cost of preparing and separating high-quality, low atomic layers of GNP.
