Dolphins inspire a new bomb-detecting system

By - October 25, 2013 1 Picture
Chances are, you know that dolphins use sonar to locate and stun prey underwater. You might also know that they create "bubble nets," in which they trap fish inside a ring of air bubbles that they blow while swimming in a circle. With all those distracting bubbles suspended in the water, though, their sonar needs to work in a special way in order to pick out the fish. Scientists have copied that sonar system, to create a type of radar that could differentiate between ordinary objects and things like explosive devices. Read More

New surface coatings give insects the slip

By - September 27, 2013 1 Picture
Not having air conditioning in my house, here's something I didn't know: the inner surfaces of air conditioner ventilation pipes are often covered in cockroaches. Nice. In order to keep the roaches out of those pipes – along with keeping other insects out of other places – scientists from Germany's University of Freiburg have developed new bio-inspired surface coatings that even sticky-footed bugs can't cling to.

Shape-changing lens blends human and insect vision

By - September 18, 2013 3 Pictures
One example of biomimicry that keeps popping up on the pages of Gizmag is the use of insect eyes as a model for innovative new optical devices. It seems that the potential for development in this area is far from exhausted with the announcement of another bug-inspired lens breakthrough from Ohio State University. This experimental lens developed by associate professor of biomedical engineering and ophthalmology, Yi Zhao, combines the wide angle properties of insect vision with the depth-of-field capabilities of a human eye.

Artificial muscles could allow robots to lift 80 times their own weight

By - September 10, 2013 1 Picture
It's a classic science fiction scene: an android is injured and its human-like exterior is laid bare to reveal the metallic gears and cables of its true mechanical nature. The future is, unsurprisingly, not likely to match this scenario as our ability to mimic biology with innovations like artificial muscles improves. The latest breakthrough in this field comes from the National University of Singapore’s Faculty of Engineering where researchers have developed a “robotic” muscle that extends like real muscle tissue to five times its original length, has the potential to lift 80 times its own weight and holds out the promise of smaller, stronger robots capable of more refined movements.

Oil spill-absorbing material inspired by cactus needles

By - August 8, 2013 1 Picture
When an oil spill occurs at sea, there are already a number of possible options for gathering the oil that floats in a layer on the water’s surface. Some of the oil also forms into tiny suspended droplets, however, which have proven much more difficult to gather. Now, Chinese scientists have developed what could be a solution – and it owes a debt to the humble cactus needle. Read More

Watery windows mimic blood vessels to boost building efficiency

By - August 6, 2013 1 Picture
Researchers at the University of Toronto say they can improve the energy of efficiency buildings by fitting window panes with tiny channels of water. The scientists says that these channels, inspired by vascular systems in nature such as the network of blood vessels in the human body, can provide 7º to 9º C of cooling in the summer, and reduce heat loss during winter.

Limbo lower now: 3D-printed STAR bot flattens itself to crawl under doorways

By - August 2, 2013 5 Pictures
Nature has been the source of inspiration for a variety of different forms of robotic locomotion. Yet another example is the STAR, a 3D-printed robot modeled after an insect's ability to squeeze into even the tiniest spaces. Developed by students at UC Berkeley's Biomimetic Millisystems Lab the STAR, which stands for Sprawl Tuned Autonomous Robot, is able to flatten its legs down to slip under a small gap and then raise them up again to climb over larger obstacles.

Give zebrafish some booze, and they stop fearing robots

By - August 1, 2013 2 Pictures
With some help from a robotic fish, scientists have discovered that zebrafish are much like humans in at least one way – they get reckless when they get drunk. OK, “drunk” might not be technically accurate, but when exposed to alcohol, the fish show no fear of a robotic version of one of their natural predators, the Indian leaf fish. When they’re “sober,” they avoid the thing like crazy. The researchers believe that the experiments indicate a promising future for robots in behavioral studies. Read More
