Circuits and Systems Society Chapter Hybrid Event | Piezoelectric Nanofiber-Based Acoustic Biosensors for Mimicking Cochlear Hearing System by Dr Wenhui Song, Professor of Biomaterials and Medical Engineering, University College London

The cochlear implant, currently used as a clinical treatment for hearing loss in children and adults, is a device that bypasses the damaged sensory receptor hair cells by generating electric current in response to an acoustic sound.

To address its fundamental limitations of size mismatch and poor biocompatibility at the electrodes-neurons interfaces, we are developing and understanding the piezoelectric properties of piezoelectric polymeric nanofibers under acoustic stimulation and also exploring bioinspired piezoelectric polymeric nanofibre-based acoustic devices and investigating their performance for potential applications in cochlear implants and hearing systems.
