Creating artificial ear has superhuman hearing

US scientists have invented a breakthrough bio-ear ear, capable of "hearing" radio frequencies far beyond the normal hearing of human ears.

>>>New technology creates fake ear like and works like real ears

The team from Princeton University used an advanced 3D printing technology to build an ear that contains electrodes that support hearing within it. It is an important step towards creating "virtual world people," which is a combination of living cells and electrical circuits, as in science fiction films, "The Terminator." " Hollywood.

Michael McAlpine, head of research and assistant professor of mechanical and aerospace engineering at Princeton University, said: "There are generally mechanical and thermal challenges when combining materials. In the past, researchers have proposed a number of strategies to transform electrodes so that the combination process is less troublesome. a new approach - building and developing biology with the coordination of electronics and in a mixed 3D mold ".

Although acknowledging the need for more research and testing before new technology can be applied to humans, Mr. McAlpine asserts that, in principle, artificial ear can be used to restore or enhance hearing. of human. The researcher added that the electronic signals emitted by the bio-ear can connect to the patient's nerve endings, similar to a hearing aid.

The system currently receives radio waves, but McAlpine has revealed that the team has planned to combine other materials, such as pressure sensitive electronic sensors, to allow the ears to memorize sounds. auditory bar.

McAlpine's team has created many improvements in recent years, involving the use of small-scale medical antennas and sensors. Last year, he and his colleagues studied the development of a "tattoo" made up of an antenna and biosensor that can be attached to the surface of a tooth.

However, the biomechanics project is the group's first attempt to create a unit with perfect functionality, not only simulating a human ability but also expanding it using the implanted electrons. add.
