Topology optimization of piezoelectric structures : micro-actuators and energy harvesters
Résumé
This paper reviews the primary research efforts
conducted within the AS2M department of the FEMTO-ST
institute, focusing on topology optimization of piezoelectric
structures. The paper primarily highlights the principle and
the possibilities offered by topology optimization with a
specific emphasis on the SIMP approach (Solid Isotropic
Material with Penalization). Then, the design processes of
piezoelectric micro-actuators and energy harvesters are described.
The optimized piezoelectric structures are presented
and the improvements over classical designs are assessed.
Finally, the paper discusses the feasibility and the potential
of multi-material topology optimization.
