Scientists Create 3D-Printed “Bionic” Ear

Scientists at Princeton University have successfully created a printable “bionic” ear, combining a small coil antenna with cartilage using “off-the-shell” 3D-printing tools and nanoparticles. Yeah, bionic. According to lead researcher Michael McAlpine, there are usually “mechanical and thermal challenges” when combining electronics with biological materials. The key to overcoming these challenges, he says, lies in …
