发帖数: 3584 | 1 Brilliant Bio-Design: 14 Animal-Inspired Inventions
http://webecoist.com/2011/01/14/brilliant-bio-design-14-animal-
inventions/
神的创造给了人类太多的灵感，我自己真的不能视而不见。
Surveillance cameras flap their wings in the sky just like birds and
bats. Tiny little hairs on gecko feet help a robot climb a smooth
vertical surface. The impact-resistant surface of human teeth inspires
light and durable aerospace materials. Just like designs inspired by the
sea, insect-mimicking inventions and buildings that look like natural
terrain, these 14 examples of biomimicry based on animal and human
biology capitalize on the unparalleled efficiency of nature.
A Robotic Arm Like an Elephant Trunk

Robotics have always been bound by the limitations of the computers of
their time, but as computer technology continues to evolve, more complex
calculations for a wider range of movements become possible. And the
capability of flexible, pliable movement has given way to more advanced
designs like this one: a new ‘biomechatronic’ handling system based on
an elephant’s trunk. Created by German engineering firm Festo, the
Bionic Handling Assistant smoothly transports heavy loads, expanding and
contracting by inflating or deflating air sacs within each ‘vertebrae’. |

Bats have unwittingly become the inspiration for a government
surveillance device. The United States military commissioned the COM-BAT
from the University of Michigan College of Engineering, giving them a
five-year, $10-million-dollar grant to develop the design. Fitted with a
solar panel in its transparent ‘head’, the 6-inch spy plane has wings
shaped like those of the flying mammal. The plane must be able to collect
large amounts of surveillance data while running on only 1 watt of power. |

“Skulls in general are extraordinary impact-resistant structures and
extremely light at the same time as they protect the most important organs
of an animal body and this performance and physical property can be
applied in structure or architecture design,” says architect Andres
Harris, who has studied animal bones – particularly bird skulls –
extensively in a bid to design a highly efficient bio-inspired surface.
Harris imagines mimicking the material for a large pavilion, and the blog
Biomimetic Architecture notes that this concept could also be applied to
cars. |

The kingfisher dives into the water from the air without making a splash,
mostly thanks to its highly efficiently-shaped beak. In a stroke of
genius, engineer and bird enthusiast Eiji Nakatsu realized that the same
shape could solve an annoying problem faced by Japan’s ultra-fast bullet
trains, which created a loud booming sound like a thunder clap whenever
they exited a tunnel. The nose of the train was pushing air at high
speeds, creating a wall of wind that not only made the loud sound, but
also slowed down the train. The new, kingfisher-inspired train nose
eliminates this problem, making the trains up to 20 percent more fuel
efficient. |

Sure, computer tech has advanced a lot in recent years – but even
supercomputers still can’t recognize human faces as well as cats can. The
University of Michigan decided to study the feline brain in order to
develop an intelligent computer. The idea is that current computers
execute code in a linear fashion, as opposed to the mammalian brain, which
can process many things at once. Lu is in the process of developing a
circuit element that behaves like biological synapses. This ‘memristor’
can remember past voltages that passed through it in a way that is similar
to memory and learning in the brain. Why cats? Computer engineer Wei Lu
says it was simply a more realistic goal than mimicking the brain of a
human. |

It doesn’t have any cool physical features that reveal its inspiration,
but the Ultracane wouldn’t be possible without study of the way bats get
around in pitch blackness. In the same way that bats can “see” in the dark
using ultrasonic echoes that reveal the location of obstacles, the
Ultracane warns blind users of objects in their path. A number of sensors
on the cane even make it possible for users to sense objects higher than
head height. |

Faster than any human-designed radio-frequency spectrum analyzer, this
radio chip also needs very little power to operate. How is that possible?
The design is based upon the human ear. MIT researchers looked at the way
the cochlea converts sound waves into electrical signals sent to the
brain. The sound waves create mechanical waves in the fluid of the inner
ear, which activate tiny hair cells that facilitate electrical signals.
Rahul Sarpeshkar used the same design principles in his artificial
cochlear radio chip, which would make possible wireless devices that can
receive cell phone, internet, radio and television signals.
““The more I started to look at the ear, the more I realized it’s like a
super radio with 3,500 parallel channels,” said Sarpeshkar. |

Here’s yet another invention to make you paranoid that that little flying
creature above your house is no ordinary bird or bat. The RoboSwift, as
implied by its name, is based upon the biology of the swift, a family of
birds capable of extremely fast flight. Developed by Delft University of
Technology, the RoboSwift is equipped with observation cameras that might
be used either to study birds, or possibly for surveillance of human
activity. Wind tunnel tests have found that its flight is remarkably bird-
like thanks to the ability to fold its ‘feathers’ backwards. |

发帖数: 3584 | 10 Stickybot: Gecko Feet Help Robot Climb
模仿壁虎的粘性机器人

How can a robot climb a smooth surface like glass without using suction
cups, which are slow and inefficient? The secret lies in the intricate
design of a gecko’s toes. Mark Cutkosky, a professor of mechanical
engineering at Stanford University, developed the ‘Stickybot’ with the
same type of dry adhesive that lets those lizards cling to the most
improbable of surfaces. This ‘directional adhesive’ relies on millions of
hairs on the ridges of a gecko’s foot with split ends that interact with
the molecules of the climbing surface.
“Other adhesives are sort of like walking around with chewing gum on your
feet: You have to press it into the surface and then you have to work to
pull it off. But with directional adhesion, it’s almost like you can sort
of hook and unhook yourself from the surface,” Cutkosky told ScienceDaily. |

发帖数: 3584 | 11 Deer Antlers Inspire Basis of Super-Tough Materials
鹿角结构成为制造超强工业材料的原理
(image via: stuart.bassil)
What makes the antlers of a deer so bone-crushingly strong? Scientists at
the University of York in the UK weren’t sure exactly how the moisture
level in deer antlers affects their strength. They studied antlers that
were cut just before the stage when stags start dueling, when they need
their antlers to be at their strongest, and discovered that during this
period, the antlers dry out. Dry, stiff materials are usually brittle and
easily breakable, but deer antlers proved to be 2.4 times stronger than
wet bone. This revelation seems to have solved a puzzling problem for
engineers: making a material that is both stiff and tough. The structure
of deer antlers will likely become the basis of incredibly durable
industrial materials. |

发帖数: 3584 | 12 Human Teeth Structure and Aerospace Technology

Our teeth are only about a strong as glass – so how can they withstand
nearly a lifetime of chomping on all kinds of hard foods? Researchers at
Tel Aviv University examined thousands of extracted human teeth and found
that under stress, the highly sophisticated structure that makes up the
exterior of our teeth forms a network of micro-cracks instead of large
ones. These tiny cracks are then able to heal over time. If engineers can
find a way to replicate this ‘wavy’, multi-layered structure in a
synthetic material, they could develop lighter and more crash-resistant
aircraft, though the self-healing properties are probably a long way from
realization. |

发帖数: 3584 | 13 Contact Lenses of the Future Inspired by Gecko Eyes

Feet aren’t the only part of gecko anatomy that’s got engineers excited.
Scientists have discovered that geckos have a series of distinct
concentric zones in their eyes that make it possible for them to see
colors at night, an ability few other creatures have. These zones have
different refractive powers, giving geckos a multifocal optical system
that allows light of different wavelengths to focus on the retina at the
same time. This makes their eyes 350 times more sensitive than humans, and
lets them focus on objects at different distances. The discovery may allow
engineers to develop more effective cameras and possibly even multi-focal
contact lenses. |

发帖数: 3584 | 14 Beer-Foam-Like Bird Feather Colors Influence Optical Materials
东方知更鸟羽毛启发下的新一代光学材料
(image via: steve patten)
The brilliantly colored feathers of the male Eastern bluebird aren’t
created by pigments, like most other colors found in nature – that shade
of blue is actually produced by nanostructures that self-assemble in much
the same way as beer foam. Essentially, they form the same way as
materials undergoing ‘phase separation’, when different substances become
unstable and separate from each other. Color-producing structures in
feathers start out as bubbles of water inside living cells, and are
replaced with air as the feather grows. These intricate optical
structures, which look like sponges with air bubbles under a microscope,
are being used to create a new generation of optical materials in the lab. |

发帖数: 3584 | 15 Human Eye Inspires Cameras with Wider Field of View
人类眼睛与宽视野相机

The curved surface of the human eye facilitates a wider field of view than
has ever been possible using a camera. The challenge for engineers was to
transfer microelectronic components onto a curved surface without breaking
them. Yonggang Huang of Northwestern University and John Rogers of the
University of Illinois built a digital camera of the same size, shape and
layout of the human eye, and developed a mesh-like material that hold
electronic components onto the curved surface. This technology would
enable photographs that are entirely clear and focused, unlike today’s
cameras which can focus only on certain areas. It may even enable the
development of an artificial retina or bionic eye. |
