Imagine a world without wires.


3/22


4/22

The latest concept in the world of technology is the

introduction of witricity.

The universal wireless charging pads were created

where you need not plug in your cell phone or ipod for

charging.


5/22

An era of a new science called nanotechnology

has evolved manipulating both atoms and

molecules and putting them into an

extraordinary degree of flexibility.

The meaning that nanotechnology holds for our

future depends on how NANOGENERATORS

solve the problem of traditional chargingtechniques!!!.


6/22

NANO GENERATORS


7/22

A huge inconvenience of having a device

loses power from lack of battery charging or

actual battery inoperability can be fixed by

several ways.

The most straightforward one being to

create longer lasting batteries that have less

of an environmental impacts.

WORKING


9/22

Wireless power supply technologies atpresent can be divided into three groups

according to their principle of operation

Electromagnetic induction

Radio reception

Resonance


10/22

The first non-contact technology achieving

widespread adoption in many portable terminals is

electromagnetic induction.

ELECTRO MAGNETIC INDUCTION


11/22

RADIO RECEPTION

Another technology very close to commercial use

makes use of the fact that energy can be

transmitted and received directly as radio waves

reception.


12/22

RESONANCE

The third principle is electromagnetic

resonance..

This specific application uses only the electric or

magnetic field, instead of electromagnetic

waves, current, etc .,


13/22

The resonance type is a proximity electromagnetic field

approach, using electric, magnetic and other fields built on

research and development.

In new areas such as near-field light, optical

communications, photonic crystals and meta materials.


14/22

Power from Close-Range:

Electromagnetic induction can transmit up to several

hundred kW of power, a considerable amount, but

only over a maximum distance of 1cm or less.

The radio wave reception approach can handle

ranges of up to about 10m, but only for low power

levels of several mW to several hundred mW.

Resonance wireless power supply, on the other hand,

can transmit power over 3 or 4m at levels of up to

several kW


15/22

Why is wireless power supply hot?

Because of

(1) market growth,

(2) developments in technology and

(3) delays in competing technologies .


16/22

WHY FIRMS SWITCHING TO WIRELESS POWERSUPPLY..??

There has been little significant technical

development in the last few years, and no dramatic

increase in capacity is expected until fuel cells enter

mainstream use.

Even if the battery life per terminal remains the same,

the increase in the number of terminals each personcarries is leading to increased dissatisfaction with the

time needed to charge them all.


17/22

THE NEXT CHALLENGE

Three objectives have to be achieved:

Eliminate the use of the AFM,

Make many nanowires generate electricity

simultaneously and continuously and

Excite the nanowires in an indirect wave, such asan ultrasonic wave.


18/22

HURDLES LYING IN THE PATH OF NANO-TECHNOLOGY

The hurdles that lie ahead in the research

include learning how to grow perfectly uniformarrays of nanowires that all produce electricity

and how to extend their working life.


19/22

THE FINAL WORD!!

Wang's wire certainly triggers a piezo-storm innano world !!!
