2. Introduction History Technology Features Limitations Future
Scope References Conclusion 3. The Nokia Morph is a theoretical
future device based on NANOTECHNOLOGY that might enable future
communication devices. Morph also demonstrates how future mobile
devices might be stretchable, flexible, transparent and self
cleaning. 4. Nanotechnology Sensing Nanoscale Grass Features of
Morph Concept : Self-Cleaning Transparent- Electronics
Haptic-Surface Wearable-Device Recycling Stretchable Spider-Silk 5.
The concept of NOKIA MORPH has been introduced to the global world
at the Museum of Modern Art (MoMA) in New York City from February
24 to May 12 of 2008 as part of the "Design and the Elastic Mind"
exhibition. The concept emerged through collaboration between Nokia
Research Center and Cambridge University Nanoscience Center in the
UK. HISTORY 6. NANOTECHNOLOGY means The science, engineering and
technology related to the understanding and control of matter at
the length scale of approximately 1 to 100 nanometers.
NANOTECHNOLOGY allows control of physical properties of
nanostructures and devices with single molecule precision. 7.
ASSUME 10000 TRANSISTORS ON A HAIR Nanostructure of morph is
similar to this. NANOGRASS, NANOSENSORS, NANOFLOWERS, NANOSCALE
MESHetc ARE THE NANOTECHNOLOGIES USED INSIDE NOKIA MORPH. 8. 1)

ENVIRONMENTAL ENABLING AN APPROPRIATE AND INTELLIGENT RESPONSE.
INORDER TO IMPROVE SENSOR AND SIGNAL PROCESING CHARACTERISTICS
NOKIA INTRODUCED NANOWIRE LITHOGRAPHY (NWL) PROCESS THAT FABRICATES
A LARGE AREA AND SELF ALIGNED 3D ARCHITECTURES. 10. ECO SENSOR
CONCEPT NOKIA 3110 EVOLVE ECOSENSOR CONCEPT CONSISTS OF TWO PARTS
1) A WEARABLE SENSOR UNIT THAT CAN ANALYZE LOCAL ENVIRONMENT AS
WELL AS PERSONS HEALTH. 2) THE SECOND PART IS A POWER EFFICENT
MOBILE PHONE. 11. 2. HAPTIC SURFACE Touch sensitive and responsive
[haptic] surface of NOKIA morph is provided by large area sensing
surfaces using piezoelectric nanowire arrays. ZnO nanowires are
used to produce the piezoelectric nanowire arrays. Buttons on the
device surface are real 3D forms. 12. A water droplet beads up on a
lotus leaf due to the hydrophobic nanostructures Double roughening
of a hydrophobic surface, on the submicron and nanometer scale,
creates superhydrophobicity. 3. SELF CLEANING NANOFLOWER The
surface of morph is superhydrophobic that makes it extremely dirt
repellent. Nanostructured surface known as nanoflowers that
naturally repel water, dirt and even finger-prints is used here.
NANOSTRUCTURED SURFACE 13. Enhanced energy density batteries
(quicker recharge ). Polymer CNT composites with controlled
conduction, nanotube enhanced supercapacitors and nano composite
solar cells etc acts as the power sources. Nanoenhanced dielectrics
as separator and high power capacitors. Energy harvesting from RF
using wideband antennas and using nano electro mechanical (NEM)
method. Microwatt level energy harvesting from waste energy in the
air. 4. ADVANCED POWER SOURCES 14. NANOGRASS NANOGRASS is used for
harvesting solar power. NOKIA developed a full solid state flexible
DYE SENSITIZED SOLAR CELL (DSSC) using ZnO Nanostructures which act
as photovoltaics For this purpose. 15. 5. STRETCHABLE ELECTRONICS
Stretchable electronics structure to allow device form factors. The
nanoscale structure of the electronics enables stretching.
Nanoscale internal structures controls the elasticity. INSIDE
ELECTRONICS AT STRETCHABLE MODE. 16. NANOWIRE LITHOGRAPHY Ni
NanoWire Lithography (NWL) uses NanoWires (NWs) as etch masks to
transfer their one-dimensional morphology to an underlying
substrate. The method relies on electrochemical deposition and
selective chemical etching. CONSTRUCTION OF NANOWIRE LITHOGRAPHY Ni
17. ZnO NANOWIRES ACT AS FLEXIBLE TACTILE ARRAYS. A nanoscale mesh
of fibers similar to spider silk controls the stretching when
device is folded. Fibril proteins are woven into a three
dimensional mesh that reinforces thin elastic structures. NANOSCALE
FIBRES STRENGTH OF SPIDER SILK 18. The whole electronic circuit
inside NOKIA morph is entirely transparent. Nanoscale electronics
becomes invisible to the human eye. 6. TRANSPARENT ELECTRONICS 19.
7. WEARABLE DEVICE Can be used a watch or a band. 20. THE INITIAL
MANUFACTURING COST IS VERY HIGH. THE EXPECTED MARKET PRICE IS
AROUND Rs 60000/-. CONVENTIONAL DSSCs PROVIDES UNSTABILITY RELATED
TO SOLVENT LEAKAGE AND EVAPORATION 21. THE SHAPES COULD BE MADE
MUCH MORE SIMPLER LIKE IN RING SHAPE. MORPH IN OPEN MODE COULD ACT
AS A KEYBOARD FOR PCs. 22. According to the developers, using
nanotechnology can lead to low cost manufacturing solutions as well
as adjustable, empowering devices, bringing us new, versatile
possibilities. These mobile devices will be flexible, stretchable
and shape changing, so that they can be easily integrated in our
everyday routines without special adjustments on our part. 23.
