Scientists have created a 3D-printed bionic ear


The combination of living tissue and electronics may one day be used to restore or even a replacement, for example, the human ear. Researchers at Princeton University, under the direction of Michael McAlpine created based on 3D-printed cell prototype artificial ear with a built-in antenna. McAlpine is developing electronics that can be integrated with the human body, has been for many years. For example, in 2011, a scientist and his team have created a kind of ” graphene tattoo “, which could be integrated with the tooth to check for bacteria. This time, he and his team went ahead and decided to set up a body with a built-in electronics.

For the production of the ear, McAlpine started with 3D-printing technology. Although the ear and can be recreated from the transplanted cartilage printing technique maximizes repeat form of the ear where it is also embedded antenna. The team used a special hydrogel, which was placed in the cells that form the outer ear. With the additional silver nanoparticles, scientists have created a spiral antenna, one end of which is connected to the theoretically cochlea, which enables us to perceive and recognize sounds.

As a result, subsequent tests revealed that the ear is capable of receiving radio waves, and with the use of a pair of ears (left and right) turns the stereo. Future versions of the bionic ear can perceive acoustic sound through other additional sensors. McAlpine said that in theory, the ear can be connected with human nerve endings, but it is, of course, require additional tests.

McAlpine hopes that further research will help to develop and move forward in the creation of bionic bodies, which will consist of sensors or other electronics, as well as human tissue.

Progress in this direction already. Eyes, for example, researchers from the University of California have already created . And the guys from the Massachusetts actively moving forward in creating artificial kidneys .
