Résumé des résultats (Abstract) (Anglais)	There is a need for implantable hearing aids for persons with severe to profound hearing loss having still some residual acoustic hearing capacity. One solution is to place a piezoelectric MEMS transducer directly at the entry of the cochlea. Such transducers are based on piezoelectric thin films and allow for adequate miniaturization. Their advantages are low voltage operation, high power density, flat amplification curve with great bandwidth (50 Hz up to 20 kHz), and cheap manufacturing if produced in large numbers. However, there are challenges in achieving an enough stable piezoelectric performance, as strongly piezoelectric thin films are also ferroelectric. The objective of this project is to increase device stability and performance over time.
