3d printed \'bionic\' ear can hear radio frequencies.

Washington, May 2ANI ): Using off-the-
Scientists at Princeton University have created a functional ear on shelf printing tools that can \"hear\" radio frequencies far beyond normal human abilities.
The main purpose of the researchers is to explore an efficient, versatile method of combining electronic products with organizations.
Scientists use 3D printing of cells and nanoparticles, and then carry out cell culture, combining a small coil antenna with cartilage to create what they call ion-free ears.
\"Generally speaking, there will be mechanical and thermal challenges in connecting electronic materials with biological materials,\" said Michael mcaping, assistant professor and lead researcher in mechanical and aerospace engineering at Princeton University.
\"Previously, researchers have proposed some strategies to adjust electronics so that the merger will not be so embarrassing.
This usually occurs between the 2D electron sheet and the tissue surface.
However, a new approach is proposed in our work.
\"In a 3D interwoven format, co-constructing and growing biology with electronic products,\" he explains . \".
McAlpine\'s team has made some progress in recent years, including the use of small-
Medical sensors and antennas.
Last year, a study led by Naveen Verma, assistant professor of McAlpine and electrical engineering, and Fio Omenetto at TuftsUniversity, resulted in the development of a \"tattoo\" consisting of sensors and antennas \", can be attached to the surface of the teeth.
However, this project is the first effort of the team to create a fully functional organ: Not only does it replicate human capabilities, but it is expanded using embedded electronic devices, creating organs using 3D printers is a recent advance;
In the past few months, several groups have reported the use of the technology to achieve this.
But this is the first time researchers have demonstrated that 3D printing is a convenient strategy between electronic organizations.
This technique enables researchers to combine antenna electrons with tissues in a highly complex topology of the human ear.
The researchers used an ordinary 3D printer to combine a gel matrix and calf cells with silver nanoparticles forming an antenna.
Calf cells later developed into cartilage.
Manu Manno, a graduate student at the mcaping lab and lead author of the paper, said additive manufacturing has opened up new avenues for thinking about the integration of electronics and biological tissue, and make it possible to create real bionic organs in form and function.
It is possible to integrate sensors into various biological tissues, for example, to monitor the stress on the meniscus of apatient knee, he said.
The researchers described their work in an article published in the academic journal Nano Letters. (ANI )
