A Polymeric Micro-Cantilever Resonator Array and Its Implications in Auditory Prostheses

Tech ID: 18879 / UC Case 2003-079-0


Ten percent of the general population suffers from hearing loss and that number rises to thirty five percent for people over sixty-five years of age. However, current digital hearing aids and cochlear implants to ameliorate hearing loss have their disadvantages. Some of these include high power consumption and long processing time associated with a large number of channels which increases its cost and size and limits its utility.

Technology Description

University of California, Irvine researchers have developed a polymeric micro-cantilever resonator array that mimics the biological front-end processing in the cochlea.


This polymeric micro-cantilever resonator array has a great potential for achieving unparalleled real-time processing with a high frequency resolution and extremely low power consumption. Their usage in hearing aid and cochlear implant applications should be seriously explored.
