3D-Printing more prosthetic ears – But this time they can hear

by hmd_webmaster, 10th May 2013

Scientists have toyed with 3d printing ear implants for ages, but they’ve usually been more cosmetic than functional. Princeton University scientists have taken things to the next level
with bionic upgrades. By chucking calf cartilage cells onto a hydrogel scaffold, together with
a fine silver nanoparticle circuit, they’ve created an ear that augments the capabilities of an ordinary human ear. In this case, it can “hear” radio waves. Total print time was a mere
fifteen minutes (ultra-fast by 3d-printing standards).

That just makes me want to go all bleeding edge and pull a Van Gogh so I can get myself one.
