Cochlear implants bring sound to millions with profound hearing loss. Today’s cochlear implants are still far from perfect, attributed to the frequency distortion issue caused by undesired stimulation and the controversial performance outcome among patients. As there is no representative model that can mimic the anatomy and the electrical properties of human cochleae, improvement is obstructed. Therefore, I developed an in vitro cochlea model using 3D printing technology. The model recapitulates human cochlear geometry, and it is sophisticatedly tuned to match human cochlear conductivity. My model is representative and able to exhibit the distinctive electrical response that happens in patients.
