• Nowadays, major buyers of semiconductor are not end-users but
electronic appliance makers such as HP, DELL, APPLE and NOKIA.
• Mobile appliance market become the largest sector in the future.
• Future nanotechnology component makers and engineers have to
consider the voice of the customers (V.O.C).

Wearable Device
• The future mobile phone will
be not only an electronic device
but also a piece of fashion
jewelry.
 The concept of “Wearable Devices” means a lot of things
 Transformable devices lead the way to foldable, sliding, and
bendable.
 Washable devices that protect the core electronics.
 Good looking design devices.

Nanotube Fabric for Stretch ability
“Fabrics enable flexibility and softness, providing a nice look and
feel and a way to customize the products hiding the hard
technology.”
 Alan B. Dalton, Ray H. Baughman, UT Dallas (Nature, 2003 )
1cm
Diameter : 100um
• A textile containing two nanotube-fibre supercapacitors woven in orthogonal directions.
• More than twice the value of steel wire in the Young’s modulus and tensile strength.
• These characteristics can provides “Stretchable” device.
5
Superhydrophobic surfaces for SelfCleaning Device
“Fabrics with self-cleaning features are examples of existing enablers for
wearable devices”
 Minglin Ma, Randal M. Hill, MIT (Science, 2006)
• Superhydrophobic: non-wettable surfaces
with high water contact angles (WCAs) and
facile sliding of drops
• Many surfaces in nature are already
highly hydrophobic and selfcleaning.
ex) Butterfly’s wing, Waxy leaf surfaces
• The ability to control the morphology of a
surface on micron and nanometer length
scales is the key

Manufacturing
The real challenge for nanotechnology topics is up-scaling
from laboratory work to industrial scale manufacturing.
 Nokia’s Manufacturability
 900,000 mobile phones a day (a phone per 10.4 sec); including 275
million electronics components
 Average prices of cell phones : $124.8
 70,000 people for manufacturing
 Printed electronics (PCB)
 Reel-to-reel manufacturing
 Low investments for factory

Environment
 The risks of nanoscale particles
 Recycle and Decomposable
We should develop new
electronics materials that are
1. easier to Recycle
2. Decomposable in biological
processes
Evidence of in vitro toxicity
• Metal oxide nanoparticles
• Carbon nanotube

Conclusion
Let’s set the targets right
Focus on
- Demanding of appliance makers
- Responsible way to bring nanotechnologies into the
public.
