Researchers create implantable mic for fully internal cochlear implants, overcoming key barriers to seamless hearing device integration.
The UmboMic sensor, made from polyvinylidene difluoride , is flexible and safe for use in the body. Their efforts led to the creation of an implantable microphone that performs like commercial external hearing aid microphones.
According to researchers, the benefits of fully implanted microphones are numerous. However, the majority of newly developed devices that detect sound through the skin or the movement of the middle ear bones have trouble recording delicate noises and broad frequency ranges. “Our goal is that a surgeon implants this device at the same time as the cochlear implant and internalized processor, which means optimizing the surgery while working around the internal structures of the ear without disrupting any of the processes that go on in there,” said Emma Wawrzynek, an electrical engineering and computer science graduate student and co-author of the study, in a statement.
