The Verge reports that Researchers led by Michael McAlpine, an assistant engineering professor at Princeton, have created a prototype artificial ear from an antenna and 3D printed cells.

While reconstructing an ear out of cartilage grafts or cultured tissue is possible, 3D printing allowed researchers to closely duplicate the shape of an ear while building in an antenna using a hydrogel seeded with calf cells for the structure, adding layers of silver nanoparticles that formed a coil antenna.

Still in the prototype stage, it is hoped that the ear will eventually be able to be attached to nerve endings, like some hearing aids.
