Testing and Characterization of next-gen PiezoMUMPS sensors

This project involves the testing and characterization of new piezoelectric vibration sensors developed by the research group led by Prof. Bahreyni at the Intelligent Sensors Laboratory. These piezoelectric sensors have now been combined with another type of sensor – one with a capacitive transduction mechanism to improve the low-frequency sensitivity and noise performance. I shall first and foremost have to design an interface circuit for each sensor and then appropriately combine these signals to generate the final output signal. This shall be followed by noise analysis involving the modeling of different noise sources that shall contaminate the actual signal for e.g, the structural housing, the electronics structure, the contributions due to the interface electronics and other environmental noise sources. Following this, mechanical characterization like resonance frequency characterization needs to be done because, if the device is used near these frequencies then rapid mechanical damage shall ensue.
