3. Transparent electronics is
an emerging technology
that employs wide band-
gap semiconductors for
the realization of invisible
circuits.

5. Transparent mobile

7.  Structure of graphene
They are so small that
cannot be distinguished by
eyes.

8. Transparent Battery
"The clear flexible plastic in
the image is a battery,
which is just 1atom thick.
The power rate
performance is strikingly
high it only takes one
minute to fully charge
the battery and it has a long
cycle life, often exceeding
1,000 cycles."

12.  transparent USB memory drive:
 Polytron Technologies has produced a
transparent USB memory stick that will come
in 8, 16 & 32GB options. The USB has an
embedded LED so that you know that it is
connected and working.

13.  ITO: Indium $92/kg(2002) $930/kg(2013) Can
only satisfy the demand till 2028 (Source:
American Mining Association 2013) Indium is
toxic!
 • Graphene: Carbon. Can be found
everywhere, very cheap, non-Toxic.

14. ITO is a ceramic material,
poor flexibility

15. Chinese ITO production: Chinese ITO demand:
Other country’s ITO demand:
Other country’s ITO production:
