Hexagonal Structure
Current density of 10ma/cm2 at4.5-5.5V/μM2
Nanoflower Boquet
Nanowire
Nanostructures with diameter of order of a nanometer ie 10-9 metres
Different Nanowires including metallic(Ni,Pt,Au),semiconduting (Si,InP,GaN),insulating(SiO2,TiO2) exists
Can be used to page link tiny components in extremely small circuits
Using nanotechnology this can be created out of chemical compounds
Nano Enabled Energy
Surface of the device can become natural source of energy
Can be achieved by covering device with Nanograss
High energy density storage materials make Batteries smaller & thinner
This batteries recharges quickly
DSSC
Researchers demonstrated new method for making a full solid state , flexible dye- sensitized solar cells
Can be an alternative to conventional silicon based photovoltaics
DSSCs pose challenges related to solvent leakage and evaporation
Nokia is trying to develop a stable DSSC based on solid electrolyte

Block diagram of Power system
Application of Nanoscale ZnO
Wearable & distinctly easy-to-use device demands an extraordinary surface
Should be low cost , environment friendly
Surface should be versatile so that the entire device is available for user interface
ZnO nanowire arrays might help in achieving this objectives
Sensing surface use piezoelectric nanowire arrays
Fabrication of ZnO Nanowire Arrays
Can be fabricated at a temperature of 70-100ºC providing compatibility with polymer substrate such as polyethylene terephtalate
By coating substrate with an array of ZnO nanowires electrical signal can be activated by mechanical force
Sensing surface & graph

A pixellated integreted system to withstand extreme deformation
Minimum strain on rigid element platforms for sensitive components
Flexible electronic structures that sustain>10% 2d stain
Stretchable Area
Flexible & Changing design
Same principle behind the spider silk
Folded design will fit in pocket or can be used as traditional handset
Unfolded larger design incorporates input devices such as touchpad & keypad input
Utilization of biodegradable materials makes production & recycling easy
Various Shapes
Self Cleaning
Self cleaning surfaces reduces corrosion , wear & improves the life
Surfaces uses nanoflowers
Nanoflowers naturally repel water ,dirt & even finger print
Zoom snap of Nanoflower
Advanced power sources
Nanotechnology enable the surface of the device a natural source of energy so that it can harvest solar power
High energy density material make battery smaller & thinner
The batteries are quick to recharge
Nanograss for solar cell
Energy storage
Sensing the enviornment
Nanosensors can sense air pollution
Identify Biochemical traces & processes
ZnO exhibits uniaxial piezoelectric response & n type semiconductor characteristic
Nokia is exploiting these qualities to achieve strain based electromechanical transducers ideal for touch sensitive surfaces
Conclusion
Device is flexible, stretchable & shape changing
Low cost
Nanosensors would raise the awareness of the people to the environment in a new way
Unfortunately, it might take nearly a decade to integrate this morph elements in to handheld devices
