Researchers from the German Kiel University have developed novel 3D printed ‘spiky-joints’ that provide wrist injury patients with a more flexible form of arm support.

Inspired by the natural wing micro-joints of the dragonfly, the spiky-joint features a novel interlocking mechanism that’s designed to cushion the wrist without impairing free movement. When set to its maximum rigidity, the scientists believe their device could be ideal for treating everyday strains and sprains, and preventing common hyperextension injuries in athletes.
