Design of in-plane piezoelectric sensors for static response by simultaneously optimizing the host structure and the electrode profile

摘要

In this work, we present a method for designing piezoelectric transducers, in a static in-plane framework, by simultaneously optimizing the ground structure and the polarization profile of the piezoelectric layers. A new idea is required to avoid the appearance of gray areas for this particular problem. Our approach is finally illustrated with numerical simulations really close to 0-1 designs.
