Artificial Hearing: From Ear Drums to Tuning Forks

EE Times Current · 7 Nov 2025 · 51m

What this episode covers

Dr. Claudia Lenk of the University of Bamberg explains her group's development of a silicon cochlea using micromechanical cantilever beams that act as artificial hair cells, offering frequency-selective sensing and adaptive feedback to improve speech recognition in noisy environments. The team is integrating these sensors with memristor-based reservoir computing for low-power hearing aid applications, a project funded by the Caritase Foundation under the name Noirosensia. The discussion also features Professor Ralph Etienne-Cummings of Johns Hopkins University, who debates the definition of neuromorphic engineering and compares Lenk's active sensing approach to other low-power AI hardware like Chi-Chi Liu's recent work.

    50. Additive Manufacturing for Eardrums and Nano-Objects

    Hosts Daniel and Forbode discuss advancements in additive manufacturing, starting with a compact 3D laser nanoprinter from Heidelberg University and Karlsruhe Institute of Technology that uses a low-powered semiconductor laser to make nanoscale printing accessible and affordable. They then explore research from the University of Cambridge, where 3D printing and machine learning are combined to create synthetic cochleas to study 'current spread' in cochlear implants. The hosts highlight how these technologies allow biologists to simulate human anatomy and understand hearing mechanics without invasive procedures.

    Episode 139: Advanced robot hearing - Christine Evers

    Christine Evers, Director of the Centre for Robotics at the University of Southampton, discusses bio-inspired machine listening that enables robots to understand complex acoustic environments. She explains how embedding human auditory processing into deep learning architectures creates efficient, interpretable models suitable for resource-constrained robots, moving away from massive, energy-hungry internet-scale models. The conversation covers the challenges of ego noise, the need for spatial awareness via microphone arrays, and the concept of 'active audition' where robot movement shapes auditory perception.

    75. Size Matters: Tiny Biomimicry Leads to Big Breakthroughs

    Hosts Daniel and Forbode discuss biomimicry breakthroughs from the University of Washington and Harvard, focusing on dandelion-inspired sensors and microscale robotic cilia. The University of Washington team created 24-milligram solar-powered sensors using Microchip's A20 Tiny processor and Kapton parachutes to deploy environmental monitoring networks via drones. Meanwhile, Harvard researchers developed self-propelled cilia from photo-responsive liquid crystal elastomers, enabling complex, programmable motion for applications in drug delivery and physical encryption.

    When your headphones listen to you with Ramses Alcaide of Neurable

    Ramses Alcaide, co-founder and CEO of Neurable, explains how his company developed Anten, a pair of headphones that use non-invasive brain-computer interface (BCI) technology to track focus and prevent burnout. Alcaide details the transition from his PhD research on EEG for ALS patients to creating a consumer product that integrates AI to boost signal-to-noise ratios from ear-level sensors. He outlines Neurable's roadmap, which includes upcoming in-earbuds and partnerships with OEMs to embed BCI into various headworn devices for both consumer productivity and enterprise safety applications.
