Chinese scientists develop world’s first bionic auditory neural interface

Chinese researchers have developed the world's first bionic auditory neural interface, a breakthrough that could significantly improve hearing restoration by enabling users not only to hear sounds but also to better understand them.

The research, led by Professor Xu Wentao of Nankai University, was recently published in the journal Nature Materials.

Unlike conventional cochlear implants, which rely on a functioning auditory nerve to transmit sound signals to the brain, the new technology acts as an artificial auditory nerve. It can detect, process and encode sound before sending bioelectrical signals directly to the brain, offering hope for patients with severely damaged or missing auditory nerves.

Researchers say the innovation addresses one of the biggest challenges in treating sensorineural hearing loss, a condition affecting nearly three percent of the global population. Current cochlear implants restore hearing but often struggle with speech recognition, particularly in noisy environments.

In animal trials, deaf rabbits fitted with the device regained hearing, responded to voice commands and completed related tasks, demonstrating the system's ability to process sound and trigger behavioural responses.

The research team said the next phase will focus on advancing the technology toward clinical trials and eventual medical use, marking a major step forward in the field of hearing restoration.
