Researchers claim that insights from cicadas' urination patterns may lead to improvements in robot and miniature nozzle design.
called cicadas, but the way they pee is even more unique. They shoot jets of urine out of their tiny frames instead of dropping drops.
“We’ve identified the fundamental constraints and forces that dictate these processes, offering a new lens through which to understand the principles of excretion, a critical function of all living systems,” said Elio Challita, a current postdoctoral researcher at Harvard University and a member of the team involved in the study, in aFor a few years, the research team hoped to have the chance to examine a cicada’s fluid secretion.
“The assumption was that if an insect transitions from droplet formation into a jet, it will require more energy because the insect would have to inject more speed,” said Challita. According to researchers, it was previously thought to be more difficult for small animals to eject water jets because it takes more energy for the animal to force the fluid out at a faster speed. Surface tension and viscous forces are to blame for this. However, a larger animal can urinate by using inertial forces and gravity.The scientists gained new insight into how fluid dynamics affects cicadas and even huge mammals because of the insects’ capacity to shoot water.
