U.S. scientists create "Bionic ear"

Scientists from Princeton University in the United States have designed a new tool in cyber: a 3D printer. This team of researchers has found a way to print-silicone ear pieces, mixed with bovine cells, filled with silver particles, which together form an antenna.
Like any other antenna, it can receive the radio signal.
3-D ear can not replace the human.
It is designed to test what can be done with the technology of 3-D printing in cyber, which is the field of combining electronics with biological tissue.
That these research director Professor, Michaal McAlpine said his team has made ​​a small step, but that their work will eventually lead to a kind of digital senses to six people, giving the human body a better opportunity to connect to electronic devices.
