GF1 - a new smart health watch with a CVD graphene touch screen

Wuxi Graphene Film, a wholly-owned subsidiary of The Sixth Elements Materials, has launched a new graphene-enhanced product in the Chinese market: The GF1 Graphene Watch. It is a smart health watch, with CVD graphene film acting as the conductive element for the touch screen (as a replacement for the usually-used ITO).

The Company kindly sent us one of these new watches to try out. So thanks! and here are our impressions: First of all, it is an attractive-looking watch, with a futuristic design and a quality feel to it. The display is a 1.3'' monochrome white OLED with a 128X64 resolution. The watch comes with an accompanying app, and includes features like pulse and heart rate monitoring, step meter, sleep quality tracking and more.

UCF team enables graphene to better absorb light

Researchers at The University of Central Florida have come up with a finding that enables graphene to better absorb light and showed more than 45% absorption of light in a single layer of graphene. This may open the door to graphene-enhanced applications that require the incident light to be fully utilized, like next-generation light detectors, touchscreens, and more.

“This is the first published work on extremely high light absorption in graphene which is tunable dynamically,” the researchers said. “Theoretical studies show further design optimization can lead to further enhanced absorption close to 90%”.

CVD Graphene prices continue to drop as commercial applications start to enter the market

CVD processes are used to create high-quality single layer (also bi-layer and tri-layer) graphene sheets. These kinds of sheets exhibit exceptional properties and can be used in a variety of exciting applications, from touch layers to transistors and sensors. For many years, CVD has been a high cost production process and this graphene is still mostly used in research projects in academic and research institutes, but prices are gradually dropping, to the point where commercial applications are starting to appear on the market.

Graphenea Monolayer CVD prices (2015-2017)

Recent years have, as we said, brought on a continuing price drop in CVD graphene prices. Spain-based Graphenea, a global CVD graphene leader, has an online shop in which it offers its high-end CVD graphene samples. We have been tracking the prices of Graphenea's CVD graphene since late 2015, and the graph above shows the price decrease.

Sussex team may use graphene to end brittle smartphone screens

Researchers at the University of Sussex have developed a new way to make smartphone touch screens that are cheaper, less brittle, and more environmentally friendly, using graphene. In addition, the new approach is also said to yield devices that use less energy and are more responsive.

The problem that the team set out to solve was that indium tin oxide, which is currently used to make smartphone screens, is brittle and expensive. The primary constituent, indium, is also a rare metal and is ecologically damaging to extract. Silver, which has been shown to be the best alternative to indium tin oxide, is also expensive. The potential solution by the University of Sussex is to combine silver nanowires with graphene, to create a new hybrid material that matches the performance of the existing technologies at a reduced cost.
