As per new findings of scientists of the Princeton University, they have created a functional ear using off-the-shelf printing tools that can hear radio frequencies far beyond the range of capability of normal human.
The scientists were intended to look for an efficient and adaptable means to combine electronics with tissue.
Lead researcher Michael McAlpine, who is an assistant professor of mechanical and aerospace engineering at Princeton, was of the view that the previous researches have shown some strategies fit the electronic so that the combination would be less awkward.
McAlpine was quoted as saying, "That typically happens between a 2D sheet of electronics and a surface of the tissue.
However, our work suggests a new approach-to build and grow the biology up with the electronics synergistically and in a 3D interwoven format".
The scientists made this functional ear by using 3D printing of cells and nanoparticles.
Then using the cell-culture they merged a small coil antenna with cartilage and named it a bionic ear.
The team of researchers made various advancements using this technology in the few passed years but the present project was the team's first effort to make a fully functional organ.
