Nose

An Analysis of Sensors and Systems of Artificial Noses

In the past couple decades, the field of artificial organs has seen immense progress, such as more comfortable prosthetic limbs and artificial livers. However, in recent years, a need for a technology able to detect the presence of molecules that the human nose cannot has emerged, leading to the creation…

The Nose: An Examination and Comparison of the Turbinate Structures of Aquatic Animals, Terrestrial Caniformia, and Humans

In recent years, researchers have studied biological systems with an engineering perspective, and have found that structures in nature are designed to respond to a specific function. The nose is one example of how evolution has formed a diversity of shapes for the same structure to accommodate the species’ needs…
