Proof-Of-Concept To Product: Initial Design Of A MEMS Sensor

How to use finite element analysis to create a piezoelectric micro-machined ultrasonic transducer.


In previous papers, we have covered how to design and verify an IoT tank fluid-level monitoring system. We covered how to create a proof-of-concept and prototype. In this series of white papers, we explore the detailed product design of the MEMS pressure sensor within this system. In this initial whitepaper, we introduce the piezoelectric micro-machined ultrasonic transducer (PMUT) sensor, show how to use finite element analysis on the device, and cover the analog front-end circuitry that converts the sensor waveform into the depth of liquid in a tank.
