High-resolution hearing delivered using latest flexible auditory brainstem implant

SMRTR summary

Scientists have developed a flexible auditory brainstem implant (ABI) that conforms to the curved brainstem surface, improving tissue contact and reducing side effects. The soft, thin-film device with micrometer-scale electrodes has shown promise in macaque testing, enabling high-resolution "prosthetic hearing" compared to rigid implants. This technology could potentially help patients with profound hearing loss who cannot use cochlear implants.
