This Presentation tells about the copying of nature in technological Products...

1. Biomimetics

2.  GECKO EFFECT
 LOTUS LEAF EFFECT
 COLOURS IN BUTTERFLY WINGS.
AREAS OF DISCUSSION

3.  Caused due to Van der Waals force, directional adhesion.
 Used for climbing on various surfaces.
 No chemical bonding involved.
GECKO EFFECT

4. DIAGRAMATIC REPRESENTATION

5.  Spatula shaped setae with lamellar surface.
 Every sq.mm contains 14,000 setae, each setae is
tipped with 100 to 1000 spatulae.
 Each setae has diameter of 5µm, each spatula is of
o.2µm long.
 Phospholipids lubricate the setae to detach before
the next step.
Description

6. .

7.  Human hair thickness varies from 18 to 180µm the
space which could hold from 12 to1300 setae.
 The length of spatula 0.2µm is below the wavelength
of visible light.
 The setae of a typical mature 70g gecko would be
capable of supporting a weight of 133kg. While each
spatula exerting an adhesive force of 5 to 25nN.
NOTES;

8.  ROBOTICS
 Gecko inspired adhesion (Directional adhesive)
 Fumble-free football gloves
 High-grip vehicle tires
 Training shoes and revolutionary rock climbing aids
ARTIFICIAL ADOPTION

9.  Caused due to Nano-structured papillae present in the leaf.
 Phenomenon exhibited – super hydrophobicity.
 Used by the plant for self cleaning purpose.
 Bio-chemical property is involved.

14.  Principle- Structural coloration.
 Color formation without pigmentation.
 Also responsible for super hydrophobicity.
COLOURS IN BUTTERFLY WINGS

 TEXTILE INDUSTRY.
 OPTICAL RESEARCH.
ARTIFICIAL ADOPTION

18.  The combination of a butterfly's structural and
pigmented colour can create interesting effects. For
example, if you saw a butterfly with yellow pigment
underneath a structure that creates a blue iridescent
colour, you might see a green shade, made by the
merging of the two colours. Or depending on your
viewpoint, you might see blue, yellow, green or a
combination of the three. Your view would change as
the butterfly moves its wings and the light enters at
different angles.
