The goal of the project was to design and integrate an efficient automated optical inspection procedure to characterize hydrophone sensor membranes for the fully implantable cochlear implant in development at the UniversitätsSpital Zurich. These membranes are a vital component of the sensor for registering sound. The goal was accomplished through the research, design, and prototyping of control systems and programs for image capture and processing. The finalized procedure is time-saving and optimized for optical inspection tests which were previously not feasible. This project lays the foundation for the fully automated optical inspection of multiple hydrophone membranes. This allows researchers to draw conclusions from data comparison to produce functional cochlear implants.
