Biomimetics involves imitating nature to address human needs. It deals with developing innovations by studying natural structures, functions, processes and systems. Nature acts as a model. Some key points of biomimetics include mimicking nature through natural or synthetic substitutes, and studying nature's solutions to problems like the lotus plant's water resistance. Biomimetics has applications in areas like energy efficient buildings, bionic vehicles, tissue engineering and more. It is a growing field with potential for developing new materials, technologies and applications.

•Biomimicry

2. WHAT IS BIOMIMETICS?
--BIOS=LIFE & MIMESIS=IMITATE
--BIOMIMETICS DEALS WITH THE DEVELOPMENT OF
INNOVATIONS ON THE BASIS OF INVESTIGATION OF
CHEMICAL/BIOLOGOCAL
STRUCTURES, FUNTIONS, METHODS,PROCESSES AND
SYSTEMS.
-- NATURE ACTS AS ‘THE MODEL’ IN OUR EFFORTS
TOWARDS ADDRESSING HUMAN NEEDS.

3. Term coined by Otto H.
Schmitt in 1969.
"taking design ideas
from nature"

4. MIMICKING CAN BE DONE BY USING
EITHER
Natural substitutes
or
Synthetic substitutes

5. Why synthetic materials?
Natural materials Synthetic materials
 Less availability  More availability
 Difficulty in isolation  Relatively easier
 Reduced amenability synthesis
 Risk of pathogen  Tailorability
transmission  Reduced risk of
 Immunogenic reaction pathogen transmission
when used as an  Biocompatibility,biode
implant. gradability .

6.  Structural
 Functional
 Structural-functional
 Biological process mimicking.

7. What can lotus teach us?
Unstickyness and hydrophobicity
unsticky or water resistant technology.

8. Nature inspired solutions are
every where….
 Energy usage buildings inspired by
termite moulds.

10. Bionic car inspired by the box
fish.

12. Bullet train motion inspired by
kingfisher.

13. Coloured butterfly wings inspired the reflective
windows.

14. Biomimic approach : In tissue
engineering
Human tissue=
Cells+ECM+signalling molecules
ECM=collagen+proteoglycan.
ECM play important role.

16. So artificial ECM can be made
for regenerating cells or tissues
Naturally by choosing collagen and
glucosaminoglycon from natural source.
Or
Synthetic mimics with similar structure or
function (ex:chitosan and gelatin hydrogel) are
used.

17. Other recent projects…
 combat.
Artificial human organs.
 human robots and
many more.
