The ability of
graphene to achieve such high temperatures without melting the substrate or the metal
electrodes is due to another interesting property:
as it heats up,
graphene becomes a much poorer conductor of heat.
Fine - tuning becomes critically important
as materials scientists test more 2 - D materials like
graphene and nanotubes for use
as electrodes.
As a potential contact
electrode and interconnection material, wafer - scale
graphene could be an essential component in microelectronic circuits, but most
graphene fabrication methods are not compatible with silicon microelectronics, thus blocking
graphene's leap from potential wonder material to actual profit - maker.
To obtain good performance with a simple process and reduced cost, we designed a modulus - gradient structure to use
graphene as both the highly sensitive strain - sensing element and the insensitive stretchable
electrode of the ECD layer.

In numerous tests, the researcher and his team investigated the nano - material
graphene, whose extremely high specific surface area of up to 2,600 m2 / g and high electrical conductivity practically cries out for use
as an
electrode material.
In September 2014 they presented the first prototype device - an E Ink display that uses
graphene as a transparent
electrode.
That 2014 E Ink display used
graphene as a transparent
electrode.
Still is good to see that more companies are joining this field, but just to be blunt: Samsung, Sony and others have shown
Graphene as transparent
electrodes years ago so it's not
as if the idea itself is revolutionary new;)
