Nanotechnology

Nanotechnology deals with structures of the size 100

nanometers or smaller in at least one dimension.

3

Nanogenerator

In simple words:

“A device that uses nanowires

for the generation of electricity is

called a nanogenerator.”

4

Construction of Nanogenerators

Nanogenerators are made up of an assembly of ZnO nanowires.

5

Architecture of Nanogenerator

Nanogenerators come in two types of structures:

VING (Vertical nanowire array Integrated Nanogenerator)

LING(Lateral-nanowire-array Integrated Nanogenerator)

Working Principle

Nanogenerators work on the principle of “Piezoelectricity”.

Piezoelectricity: Electric polarization in a

substance resulting from the application of mechanical stress .

DIFFERENT WAYS TO GENERATE ELECTRICITY VIA NANOGENERATORS

12

Vibration Energy

Image shows a hamster wearing a jacket on which nanogenerators are attached. The generators produce electricity as the animal runs and scratches.

13

Mechanical Energy

14

Hydraulic Energy

This includes harvesting energy through blood flow or body fluids ,

which then comes under bio nanogenerator.

15

Bio Nanogenerator

A bio-nano generator is a nanoscale electrochemical device drawing power from blood glucose

in a living body

Basic principle

“Taking mechanical energy from our body glucose and convert it to electrical energy for powering

devices inside the body.”

18

Mechanism of Bio Nanogenerator

The mechanism of bio nanogenerator is

much the same how the body generates energy from food.

To achieve the effect, an enzyme is used that is capable of stripping glucose of its electrons, freeing them for use in electrical devices.

HOW MUCH ENERGY OUR BODY CAN PRODUCE?

21

Energy our body produces

MECHANICAL ENERGY

Blood flow: 0.93 watts

Exhaling: 1.00 watts

Inhaling: 0.83 watts

Walking: 67.0 watts

ELECTRICAL ENERGY

Blood flow: 0.16 watts

Exhaling: 0.17 watts

Inhaling: 0.14 watts

Walking: 11.4 watts
