HOW WE’LL HAVE MORE COMPACT ELECTRONIC DEVICES
Using an inkjet printer and creating sophisticated devices with small
modification to the printer have amazed all the science buddies. We
recently have come across the invention when some researchers have made
electronic circuits by printer using metal as ink. Now it is the time to get
enthralled again with this research when some Engineers uses inexpensive
printer to produce microscopic structures that uses light in metal to
carry information.
Within such microstructure, this technology led to control electrical
conductivity. This could be used to rapidly fabricate superfast components
in electronic devices and making wireless technology faster or print
magnetic materials.
WHAT WE KNOW PRESENTLY:-
Currently, all the science buddies know that high speed internet and other
data transfer techniques are based on light which is transmitted via optical
fibres. Optical fibres carry data with high band width of light. However
when these fibres are shrunk into small spaces there is more space left for
more optical fires accommodation and therefore more data transfer. But
there occurs a limit, capability of a particular fibre decreases because light
carrying data is squeezed into smaller spaces. In contrast, electronic

circuits can be designed at smaller sizes on silicon wafers though electronic
data operates at lower bandwidth frequencies. This reduces the data
amount carried by them.
THE RESEARCH AND FINDINGS:-
The recently technology fills the gap between optical and electronic data
transfer and is calledplasmonics. It involves crowding light into surfaces
with far smaller dimensions than its wavelength. Data can be transferred
with higher frequencies like terahertz frequencies. These terahertz
frequencies lie between microwave and infra-red region of light spectrum
including X-rays, visible light and gamma ray.
Metals like gold and silver are proving good plasmonic materials because
they ameliorate this crowd effect. This plasmonic technology can create
plasmonic devices which have the potential to make wireless devices work
lightning fast speed. The Bluetooth presently operates at 2.4 gigahertz
frequency can work 1000 times faster by using this plasmonic technology.
HOW & WHY COMMERCIAL INKJET PRINTER GOT
INVOLVED?
Using the commercial inkjet printers with two cartridges filled with silver
and carbon ink researches printed 10 different plasmonic structures having
a periodic array of 2500 holes with varying sizes and spacing on a 2.5inches
by 2.2 inches plastic sheet. The researchers could control the plasmonic
arrays electrical conductivity by varying the amount of silver and carbon
ink.

plasmonic molecular structure
Using a mere 60 dollar inkjet printer they have developed a cheap and
widely applicable method to produce plasmonic materials. With it we can
draw and print the exact structures we want, without the million dollar
instrumentation used to fabricate such type of structures. Let me tell you
friends that, presently plasmonic arrays are created adopting micro-
fabrication technique which is expensive and create one at a time.
They used terahertz imaging to measure the effect of printed plasmonic
arrays of holes in a metal layer. It resulted in resonance which is machine
the external frequency with the natural frequency of the material giving rise
to peak amplitude. They observed that by varying the amount of carbon-
silver ink could be vary transmission through this structure.
ADVANTAGES:-
These faster plasmonic arrays could prove applicable for:
– Wireless devices, because the arrays permits data to be transmitted much
faster.
– Printing magnetic materials for greater functionality in myriad devices.
This technology is more than five years away.
They used 2 type of ink and upto 4 can be used at a time depending upon
the application. Technology has reached that far.
