1. Introduction
Biomimicry is a field in which scientists, engineers, and even architects study models and
concepts found in nature, and try to use them to design new technologies. Biomimicry in most
cases had a great success because the natural systems being forced by Evolutionary pressure to
become highly optimized and efficient – Natural systems materials solution serve as a guide.
One of the early examples of biomimicry was the study of birds to enable human flight. The
Wright Brothers, who finally did succeed in creating and flying the first airplane in 1903, also
derived inspiration for their airplane from observations of pigeons in flight. There are a lot of
examples we can say for biomimicry. In this paper we concentrate on three applications being
developed using the concept of biomimicry.
WATER STRIDER
This one aims To develop a microrobot that takes advantage of the surface tension of water to
stay and maneuver on water with power efficiency and agility.
Usually surface tension tends to prevent the water's surface from breaking, and the robot's legs
from sinking in.
Carnegie Mellon University mechanical engineer Metin Sitti inspired by the insects floating on
the water investigate different materials and leg shapes to improve the ability of the robot to float
on water and maneuver.
Finally he made it. The robot's body is made of a super-light carbon fiber material. Its steel legs
are coated with non-stick Teflon to repel water. A tiny battery gives it power.
Fish robots
Fish robots are to control the environment for pollutants and providing feedback about the
condition of the waters.
These robots mimic the undulating movement of real fish and are equipped with tiny chemical
sensors to find the source of potentially hazardous pollutants in the water, such as leaks from
vessels in the port or underwater pipelines. When they recharge their batteries via a “charging
hub” they will be able to transmit the information to the port’s control center. which will mimic

efficient solar panels
Many plants are heliotropic, gradually tilting towards the sun to optimize solar energy capture.
From an expressive standpoint, a solar panel that tilts towards the sun (like a sunflower) are more
efficient at generating power than those that are mounted in a fixed position.A team of three MIT
students (Forrest Liau, Vyom Sharma, and George Whitfield) designed such a system.
Heliotropic flowers track the sun’s motion across the sky from East to West. During the night,
the flowers may assume a random orientation, while at dawn they turn again towards the East

2. where the sun rises. The motion is performed by motor cells in a flexible segment just below the
flower, called a pulvinus.
Some solar tracking plants are not purely heliotropic: in those plants the change of orientation is
an innate circadian motion triggered by light, which continues for one or more periods if the light
cycle is interrupted.Leaf heliotropism is the solar tracking behavior of plant leaves. Some plant
species have leaves that orient themselves perpendicularly to the sun’s rays in the morning
(diaheliotropism), and others have those that orient themselves parallel to these rays at midday
(paraheliotropism). Floral heliotropism is not necessarily exhibited by the same plants that
exhibit leaf heliotropism.
Conclusion
In this paper ,we have concentrated only on biomimicry in the field of nanotechnology. But there
are many other things yet to be learnt from her. There is a big basket full of ideas but only few of
those have been accomplished so far in practice. Hence we engineers have to join hands together
and discover more in this field. It is our duty to unfasten the mysteries behind the various natural
phenomena. This would definitely help us to march towards a new world.
