Key Points: A multidisciplinary team of researchers creates implantable microphones for cochlear implants. Existing implants rely on external hardware. The new UmboMic uses biocompatible piezoelectric material to capture eardrum movements. The new microphone targets a part of the middle ear called the umbo, which vibrates unidirectionally, making it easier to sense these movements. Testing on human ear bones from cadavers demonstrated robust performance. The team aims to ensure the sensor remains flexible and effective for up to 10 years. A multidisciplinary team of researchers from MIT, Massachusetts Eye and Ear, Harvard Medical School, and Columbia University has developed a groundbreaking...
