Eardrum transducer with nanoscale membrane

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a miniature transducer that can be directly attached to the human eardrum. The core idea is to use a nanoscale membrane coupled with a piezoelectric material and specialized electrodes to efficiently transfer audio signals by generating focused surface acoustic waves. These waves are transmitted from the device's nanoscale membrane to the eardrum, enabling clear and energy-efficient hearing assistance.

Use CasesContent extracted from patent full text and abstract with AI.

• Hearing aids that are tiny, light, and more energy efficient than current models, capable of being placed directly on the eardrum.
• Cochlear or middle-ear implants for restoring or enhancing hearing in individuals with hearing loss.
• Invisible audio receivers for discreet communication (e.g., in security, performance, or military settings).
• Medical research devices to study eardrum function and auditory transduction.
• Wireless in-ear devices for augmented reality or high-fidelity personal audio applications.

BenefitsContent extracted from patent full text and abstract with AI.

• Direct energy transfer to the eardrum provides higher efficiency and better sound quality than air-based transducers.
• Very small, lightweight, and unobtrusive design is possible, minimizing user discomfort and maximizing cosmetic acceptance.
• The nanoscale membrane allows precise control over vibration and ensures improved signal coupling, leading to clearer audio.
• Lower power consumption can extend battery life in hearing devices.
• Biocompatible coatings enhance safety for long-term use within the ear canal.
• Multipoint stimulation using arrays of membranes can tailor acoustic profiles to individual patients, potentially improving performance for diverse forms of hearing loss.
