Biomimicry

Lampreys can stick to speeding sharks, so you'd think they could teach us a thing or two about suction. It turns out that they can indeed, as scientists have developed a lamprey-inspired suction cup that can lift over 800 times its own weight.

When it comes to systems for cleaning up marine oil spills, most of them simply float in place, waiting for the oil to come to them. A new robot, however, could proactively move through oil slicks – and it's inspired by both a dolphin and a sea urchin.

If someone asked you to move like a robot and you responded with the fluid art of ballet, your audience would be baffled, yet technically, you would be right. Robots are famous for their characteristic rigid movement, which is useful in some applications but can hinder adaptability. Now, researchers have developed a robotic wing that moves like no other.

Li-ion batteries need complex cooling systems. Yet, the human body, which generates enough heat to boil over 100 cups of tea daily, is literally just chillin’. The secret? Our skin’s ability to sweat. Scientists may have given batteries this ability.

Many readers will remember the MetaFly, a remote-control robotic insect that flies by actually flapping its wings. Well, its inventor is back with a much more capable robotic swift (you know, the bird), which is currently on Kickstarter.

The new “stingraybot” from a team at ETH Zurich (the Federal Institute of Technology of Switzerland) offers enormous promise for surgery, medical care, wildlife biology, robotics, and more, thanks to muscular membranes of microbubbles.

Georgia Tech takes vision for soft robots to the next level with PHySL, a biomimetic photo-responsive hydrogel soft lens that focuses using light alone. It does away with electronics, wires, bulk, and the dangers of breaking.

An experimental robotic gripper from Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL) utilizes a pair of lobster tails as twin fingers. Because it uses actual animal tissue, this “hand” isn’t bio-mimicked. It’s bio-derived.

A human-metabolism-inspired biofuel cell uses glucose and riboflavin to deliver 20 times more energy than similar previous tech. Made from cheap, eco-friendly substances, it offers energy storage for a world craving electrification.

Blurring the line between biology and robotics, Chinese scientists are taking biomimicry to new depths with a small, low-energy bionic jellyfish that's so lifelike in form and movement it’s almost indistinguishable from the real thing.

Despite the fact that they bang their heads against trees on a daily basis, woodpeckers don't suffer brain injuries. Inspired by the tough-headed birds, scientists have developed a fixed-wing drone that can survive frontal collisions.

In contrast to other underwater jet packs, the Kikfin Shark has a full set of fins to bio-mimic fast, nimble sea creatures for superior movement and agility. It's as close to morphing into an actual man-shark as the current state of science allows.
