American engineers make a mechanical substitute for the cocktail, the ear snail.
The use of similar micromachining techniques for the realization of integrated circuits has allowed the manufacture of this mechanical ear, which allows to produce large quantities of grain in a relatively adequate way. But before starting, they want to improve the sensitivity of the tool.
The mechanical cochlea functions as the real. The cochlea is a spiral structure of the inner ear.
It consists of several tubes in which there is a liquid similar to water. When sound arrives, it produces waves in this liquid, the waves move a membrane and this movement becomes a signal (electric current) of sending to the brain.
