INTRODUCTIONINTRODUCTION

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.

HISTORYHISTORY

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.

TECHNOLOGYTECHNOLOGY

NanotechnologyNanotechnologyNANOTECHNOLOGY 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.

1. 1. SENSINGSENSING

OBSERVE OUR LOCAL ENVIRONMENT THAT INCLUDES ANALYZING POLLUTIONS ,TEMPERATURE etc.

NANOSENSORS CONSTRUCT A COMPLETE AWARNESS OF THE USER CONTEXT –BOTH PERSONAL AND 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.

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.

2. 2. HAPTIC SURFACEHAPTIC 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.

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

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. 4. ADVANCED POWER SOURCESADVANCED POWER SOURCES

NANOGRASS

SUN RAYS

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 photovoltaicsFor this purpose.

5. 5. STRETCHABLE ELECTRONICSSTRETCHABLE ELECTRONICS

Stretchable electronics structure to allow device form factors.

The nanoscale structure of the electronics enables stretching.

Nanoscale internal structures controls the elasticity.

NANOWIRE LITHOGRAPHYNANOWIRE 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.

The whole electronic circuit inside NOKIA morph is entirely transparent.

Nanoscale electronics becomes invisible to the human eye.

KAIST’S TRRAM

TRRAMTRRAM

Transparent Resistive Random Access Memory (TRRAM) developed by Korean Advanced Institute of Science and Technology (KAIST) as the major platform for the transparent electronics concept of morph.

By integrating TRRAM device with other transparent electronic components a total see through embedded electronic system could be developed.

TRRAM records data by changing the resistance of a metal oxide film known as Resistive Ram.
