This project focuses on the testing and characterization of MEMS piezoelectric accelerometers designed for aerospace applications. These devices are critical for monitoring vibrations in mechanical systems such as turbines and rockets. However, the lack of electromagnetic shielding and device fragility pose challenges for obtaining accurate and reliable measurements. To address these issues, we developed a refined testing protocol using an isolation box to minimize electromagnetic interference and ensure stable readings. The project tested seven devices using a calibrated shaker over a range of frequencies and amplitudes to validate device performance and identify inconsistencies. The findings provide insights into device sensitivity, responsivity, and areas for improvement in testing protocols.
