It looks like nature has stepped into the gear manufacturing market:

The First Gear Discovered in Nature - Popular Mechanics

With two diminutive legs locked into a leap-ready position, the tiny jumper bends its body taut like an archer drawing a bow. At the top of its legs, a minuscule pair of gears engage—their strange, shark-fin teeth interlocking cleanly like a zipper. And then, faster than you can blink, think, or see with the naked eye, the entire thing is gone. In 2 milliseconds it has bulleted skyward, accelerating at nearly 400 g's—a rate more than 20 times what a human body can withstand. At top speed the jumper breaks 8 mph—quite a feat considering its body is less than one-tenth of an inch long.

The article states they observe gear failures due to broken teeth in the adults.

These render the affected insects incapable of future jumping.

:lol:

very interesting. And they're conformal gears, not hypocycloidal. Very interesting.
