Engineers Help Discover the Surprising Trick Jellyfish Use to Swim

Engineers Help Discover the Surprising Trick Jellyfish Use to Swim | Biomimicry | Scoop.it

"Millions of years ago, even before the continents had settled into place, jellyfish were already swimming the oceans with the same pulsing motions we observe today. Now through clever experiments and insightful math, an interdisciplinary research team has revealed a startling truth about how jellyfish and lampreys, another ancient species that undulate like eels, move through the water with unmatched efficiency."

Underwater Vehicle Uses a Balloon to Dart Like an Octopus

Underwater Vehicle Uses a Balloon to Dart Like an Octopus | Biomimicry | Scoop.it

"When you inflate a balloon and then release it without tying the valve shut, it certainly shoots away quickly. Octopi utilize the same basic principle, although they suck in and then rapidly expel water. An international team of scientists have now replicated that system in a soft-bodied miniature underwater vehicle, which could pave the way for very quickly-accelerating full-size submersibles."

Artificial Jellyfish 'Medusoid' Swims in a Heartbeat: Creation is an Amalgam of Silicone Polymer and Heart Muscle Cells

Artificial Jellyfish 'Medusoid' Swims in a Heartbeat: Creation is an Amalgam of Silicone Polymer and Heart Muscle Cells | Biomimicry | Scoop.it

Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish.

Underwater Fin Could Break Speed Record

Underwater Fin Could Break Speed Record | Biomimicry | Scoop.it

"Animal Dynamics, a company formed of biomechanics from the University of Oxford’s Department of Zoology, islooking to break the human-powered water speed record in a canoe propelled by an underwater fin, mimicking the way that dolphins or whales swim. The team believes that a flapping fin design could be a more efficient than a traditional propeller mechanism, as it works with the natural flow of water, rather than against it. Instead of using paddles, the catamaran-style canoe has a hydrofoil under its bow which is operated by a driver using a pedaling system. The cycling motion drives a fin downwards through the water, creating the thrust to propel the canoe forwards."

Octopuses Inspire 3D-printed Propulsion Systems for Boats

Octopuses Inspire 3D-printed Propulsion Systems for Boats | Biomimicry | Scoop.it

"Octopuses and squid are amazing animals. Their unique attributes have already inspired invisibility cloak technology and more comfortable medical implants. Now, their ability to flee quickly from predators has inspired a new propulsion system for boats and other water craft."
