Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability. The researchers' primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The scientists used 3D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear.
