Fine-Tuning the Design of Piezoelectric Transducers with Simulation

Mads Herring Jensen April 5, 2019

A variety of use cases and a variety of physics: Piezoelectric transducer designs need to account for electric currents, pressure acoustics, stress-strain, and acoustic-structure interaction.

It’s not just science fiction: Objects really can levitate. 1 way this is possible is by using sound waves to lift and suspend particles midair. Simulation can broaden the use of this technology.
