INTRODUCTION

• Our life style is completely dependent on electricity.

• Scarcity of electric energy is not so far.

• We have to think of new methods for generation of electricity for different

purposes.

• Researches proved that sweat can be used to produce electricity

HISTORY

• It is one of the newly developed technology.

• Researchers from University of California & American Chemical Society is

working on power generation from sweat.

• Joseph Wang presented the idea, in the 248th National Conference of American

Chemical society.

• With the help of an enzyme they generated power from human perspiration.

LITERATURE REVIEW

Batteries produce energy by passing current and the ability to generate electrical

power from human perspiration through the use of epidermal tattoo bio-fuel

cells.(‘Angewante Chemie’- Dr. W. Jia and et all).

7

BASIC PRINCIPLE

• It works on the principle of harnessing the electrons, during lactate

oxidation, in an enzyme mediated reaction.

8

COMPONENTS

A simple tattoo

Lactase oxidase enzyme at anode.

Platinum black at cathode.

9

CONSTRUCTION

TATTOO TYPE:

• Carbon forms the base for the

tattoo.

• Anode is a matrix of TTF-LOx-

Chitosan.

• Cathode consist of platinum black

coated with Nafion layer.

10

WORKING

• During intense physical activity, sweat gland produce sweat , which contain lactate.

• Lactate is oxidized by LOx .

• TTF(tetra thio fulvalene) is employed to promote low potential oxidation.

• Chitosan layer above LOx prevents its efflux.

• Nafion layer prevents direct platinum skin contact .

• The resulting electron flow is exploited to produce electricity, by means of anode and cathode provided.

• Energy can be extracted by means of 2 leads – one at anode and other at cathode , connected to a battery.

Biological reaction

12

MERITS

• Mobile phones can be charged while doing exercise.

• External power supply is not required .

• Does not cause skin irritation.

• Conventional energy sources can be preserved.

• Tiny, temporary, removable, external, inexpensive.

• Safer renewable source- no leakage of toxic chemicals

13

DEMERITS

• Elasticity against mechanical stress and strain.

• Possible for low voltage application only.

• Lots of work is to be done in this field.

14

APPLICATIONS

• Recharge mobile phone bytapping into the energy fromperspiration.

• Implementing as wrist

bands & head bands

15

FUTURE ASPECTS

• We can hope for a more efficient production of power from artificially produced

sweat.

• It will cause revolution in the field of the renewable sources.

16

CONCLUSION

• Power from human perspiration creates a new era with saving electricity.

• A lot of research is to be done in this field.
