NANOROBOTS IN HEART SURGERY

ABSTRACT :-

The evolution

and revolution of Nanotechnology

activities is increasing in all the area

to fulfill the human applications.

Nanotechnology is defined as a

technology, which is used to

produce the objects in nanometers

(10^-9) that is one

billionth.

Using that

much of

Nanotechno

highly used

in

field to

remove the

without

interference

. In the

polluted

environmen

t most of

the humans

are affected

by heart

block. The

Nanotechno

logy is

helped to

reduce the

effect of heart block. In

that case, Nanorobotics is

an important one for this

application. Nanorobotics

is a robot, which enable to

clear this blockage by

applying external control.

Nanorobotics is designed

to different techniques.

The Nanorobotics will

send to the affected area

by means of injection to

our human body. By this

method , it is also used

to reduce the allergy after

the operation. In this

paper we are dealing with

nanorobotics.

We

have to find a way to

introduce

nanorobots into the

body for surgery and

allowing it to do the

operation without

considered to be a

POSITIONING :-

To

know the location of

nanorobots where it

goes we use

ultrasonic technique.

Nanorobots must be

able to produce

ultrasonic waves by

passing a signal to

piezoelectric

membrane, which is

in built with the

device. Several

signals processing

techniques are

used to track this

ultrasonic signal

and finding the

location at any

time. Instead of

ultrasonic wave we

use infrared ray for

signal processing.
