Researchers have created new hearing implants, which could be used to offset inner ear damage. Scientists have tested the hearing implants on mice, and the team has also created a human-sized version. However, more research will be needed before the device undergoes human testing.
The hearing implants are a comfortable electrode implant, which is comprised of safe platinum. The platinum material is able to address issues of stiffness which have hindered other designs, which is due to the micron-level matching properties that platinum has. Once the platinum is wrapped in silicone it is a highly conductive material, that is able to sit adjacent to the auditory brain stem. This allows it to send out more targeted auditory signals than other hearing implants.
