Researchers at Princeton University have created a fully-functional "bionic" ear. Using a 3D printer, scientists have created an ear that hears radio frequencies a million times higher than the human ear. Michael McAlpine, lead researcher on the project, had this to say about its purpose: The idea of this was: can you take a normal, healthy, average human and give them superpower that they wouldn't normally have?
To create the ear, McAlpine and team used a 3D printer to print the cells and combine them with a small coil antenna. The materials were then placed in a petri dish where the cells cultured for 10 weeks. The end result: a "bionic" ear with embedded electronics. To see how the ear was created or for more information, read this article.
