Core Insights - The article discusses advancements in auditory technology, specifically a new bionic intelligent hearing system developed by a research team led by Professor Wenhui Song from University College London, which addresses the limitations of traditional hearing aids and cochlear implants [1][3]. Group 1: Challenges in Current Hearing Devices - Traditional hearing aids and cochlear implants amplify sound but require frequent adjustments and have high power consumption, especially in noisy environments [1]. - Current cochlear implants have only 0.04% of the neural pathways of a natural cochlea, leading to poor frequency resolution and affecting patients' sound perception and speech recognition in complex environments [1]. Group 2: Innovative Solutions - The new bionic intelligent hearing system utilizes piezoelectric nanofibers and artificial intelligence to process sound, mimicking the human auditory system's ability to capture, process, and understand sound [1][2]. - The system features an asymmetric spiral trampoline-like piezoelectric nanofiber array (ST-PiezoAD) combined with deep learning algorithms for three-dimensional sound source localization [2]. Group 3: Technical Specifications and Performance - The system employs high-performance piezoelectric materials such as PVDF-TrFE and BaTiO3 nanocomposite fibers, designed to replicate the cochlear membrane's function of converting sound waves into neural signals [2]. - Experimental results indicate high accuracy in sound source localization and the ability to perform complex auditory functions like speech recognition and music conversion [2]. Group 4: Future Prospects - The research signifies a significant step towards next-generation AI hearing devices that can autonomously capture and interpret sound, potentially improving the quality of life for individuals with hearing loss [3]. - The team is working on miniaturizing the device and increasing the number of nanofiber channels to enhance sound perception quality, aiming to approach the performance of natural cochlear membranes [3].
