In this paper, a novel electronic cochlear model is presented based on design philosophies of an ergodically enabled sequential logic (ESL) biomimetic circuit. It is shown that the presented cochlear model can reproduce key characteristics of typical nonlinear sound processing functions of mammalian cochleae: combination tone generation and pitch shift effect....
No actionable change — this is early-stage biomedical engineering research with no direct clinical application at this time.
Hardware-efficient biomimetic cochlear circuits could eventually underpin the next generation of ultra-low-power cochlear implant processors and hearing-aid chips, making this a foundational engineering advance for the field.
- 01Novel ESL (ergodically enabled sequential logic) circuit design mimics nonlinear cochlear mechanics.
- 02Hardware efficiency is a primary design goal, targeting low-power implantable or wearable applications.
- 03Published in IEEE Transactions on Biomedical Engineering (ahead of print, 2026).
- 04Work is at the circuit/simulation stage — no human or animal implantation reported.
- 05Represents a potential building block for future cochlear implant or hearing-aid processors.
The proposed ESL biomimetic circuit is hardware-efficient compared to existing electronic cochlear models.
