Princeton University graduate student Manu Mannoor holds a bionic ear as another is printed on a 3-D printer in Princeton, N.J. Mannoor is one of the scientists at Princeton University who have created an ear with an off-the-shelf 3-D printer that can "hear" radio frequencies far beyond the range of normal human capability. The researchers used 3-D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear.

PRINCETON, N.J. — With a 3-D printer, a petri dish and some cells from a cow, Princeton University researchers are growing synthetic ears that can receive — and transmit — sound.
