Enter the Cyborgs!

A team of researchers at Princeton University have reportedly create a fully functioning cyborg ear, that can “hear” radio frequencies beyond the range of normal human capability.

The bionic ear was created by merging human tissue with electronics using 3D printing tools including an off-the-shelf 3D printer. The research which Princeton’s research team claims is the first attempt of its kind, to create a fully functioning organ, could someday be used to restore or enhance human hearing.

Using 3D printing technology it was possible to merge small antenna (silver nano-particles  with cartilage  (a hydro-gel and calf cell matrix which develops into cartilage).

Much like a hearing aid electrical signals produced by the ear would be connected to a persons nerve endings, via two wires leading from the base of the ear which are wound around the part that senses sound and connects to electrodes.

Princeton researchers believe that the design and implementation of cybernetics has the potential to generate customized replacement parts for the human body. Ability to combine electronics with human tissue further allows for the creation of organs beyond the traditional capabilities of human biology.
