Segmented hinges in the long, thin bones of fish fins are critical to the incredible mechanical properties of fins, and this design could inspire improved underwater propulsion systems, new robotic ...

Figure 1: Nerve staining in the pectoral fin rays. Figure 2: Fin ray bending resulted in increased activity of the pectoral fin nerves. Figure 3: Nerve activity reflected the speed of fin ray ...

Applying curvature to the base of a fish fin can increase its stiffness, an effect that could underlie the maneuverability of fish and provide a new design concept for robotic swimmers, engineers have ...

The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish's swimming behavior, according to new research. The researchers found ...

PROVIDENCE, R.I. [Brown University] -- Pizza enthusiasts know well that a simple u-shaped curvature at the crust can keep a thin slice from drooping over when lifted from a plate. A team of engineers ...
