Graphene, Nanotechnology, and Programmable Interfaces; Samsung Galaxy Demo

I've been intrigued by graphene's multiple possibilities for the future. It is a flexible, programmable material that harness nano-technology to create flexible touch screens, "wearables", efficient energy storage systems, and more.  The following videos provide just two examples of graphene's potential.  

The details?  If you are curious, follow the links at the end of this post.  




Here is a short clip of a demo of a graphene touch screen on a Samsung Galaxy:

Graphene: Flexible touch screen, made from a sheet of carbon the thickness of one atom!

Catching up on reading the MIT Technology Review, I came across an article written by Nidhi Subbaraman about the use of graphene to make flexible displays:

Flexible Touch Screen Made with Printed Graphene:  Sheets of atom-thick carbon could make displays that are super-fast

The most recent version of graphene was created by researchers in Korea at the Sungkyunkwan University, in collaboration with Samsung.  According to the article, graphene was discovered over thirty years ago, but only recently have researchers been able to produce it in large mono-layers. This flexibility looks like it will have possibilities for future display applications, as noted in the video clip below the photos.

Roll-to-roll production of 30-inch graphene films for transparent electrodes
Nature Nanotechnology 6/20/2010

ABSTRACT:
"The outstanding electrical¹, mechanical^2, 3 and chemical^4, 5 properties of graphene make it attractive for applications in flexible electronics^6, 7, 8. However, efforts to make transparent conducting films from graphene have been hampered by the lack of efficient methods for the synthesis, transfer and doping of graphene at the scale and quality required for applications. Here, we report the roll-to-roll production and wet-chemical doping of predominantly monolayer 30-inch graphene films grown by chemical vapour deposition onto flexible copper substrates. The films have sheet resistances as low as ~125 Ω □⁻¹ with 97.4% optical transmittance, and exhibit the half-integer quantum Hall effect, indicating their high quality. We further use layer-by-layer stacking to fabricate a doped four-layer film and measure its sheet resistance at values as low as ~30 Ω □⁻¹ at ~90% transparency, which is superior to commercial transparent electrodes such as indium tin oxides. Graphene electrodes were incorporated into a fully functional touch-screen panel device capable of withstanding high strain."

Rhizome 2009: A Lovely Interactive Multi-touch App on a Flexible Lycra Screen

Loran Bey is a member of the NUI group. He created Rhizome 2009 using Unity 3D and tBeta, now know as CCV (Community Core Vision). The screen in the video is made from flexible lycra, and this provides a tangible interaction effect. The music in the background is Aphix Twin's Avril 14th.

Unity 3D is a game development tool for browser-base games, including games optimized for the iPhone. (If you visit the Unity 3D website, be sure to download their 3D web plugin and visit their relaxing on-line Tropical Paradise.)

The screen displayed in the video was inspired by the 2005 Khronos Projector installation, by Alvero Cassinelli, an assistant professor at the Ishikawa Komuro Laboratory at the University of Tokyo. Khronos is described as a "video time-warping machine with a deformable screen."

The Khronos Projector website provides several simulation applets built with Processing that you can play with. They were fun to interact with on my HP TouchSmart PC. I liked Behind the Door the best.

The following video demonstrates how the Khronos application works:


Take a look at Alvaro Cassinelli's archive of his interactive media art if you have the chance!

Cassinelli's Meta-Perception research group is doing some interesting things, too:

"The goal of this group is to research methods for capturing and manipulating information that is normally inaccessible to humans and machines. In doing so, we hope to create new ways of perceiving the world and interacting with technology. Our research methods span fields such as human-computer interaction, media arts, physiology, and ethics."
