Several micro devices, such as micro-mirrors, are subjected to working conditions featuring alternating loadings that can possibly induce fatigue in the thin metal layers, which represent critical structural parts. The quantification of the degradati

Piezoelectric thin films have gained attention as key materials for the actuation of micro devices since they provide high drive forces compared to others actuation mechanisms. One of the most challenging application field is the design of quasistati

MEMS mirrors are used in projection systems based on Laser Beam Scanning LBS and hence they are involved in applications as Augmented Reality Headset and LiDAR. Characterization of the electro-mechanical behavior of MEMS structures plays an important

In this work, we address the simulation and testing of MEMS micromirrors with hardening and softening behaviour excited with patches of piezoelectric materials. The forces exerted by the piezoelectric patches are modelled by means of the theory of fe

The work presents a novel closed-loop control to improve scanning linearity in piezoelectric micromirrors with embedded Lead-Zirconate-Titanate (PZT) actuation and piezoresistive sensing. The system includes two feedback loops aimed at pushing the co

Piezoelectric materials guarantee enhanced linearity and lower actuation voltages compared to electrostatic actuation in MEMS. However, when large displacements are desired, strong material nonlinearities arise and they should be efficiently modeled

This paper introduces a novel model to predict the dynamic response of piezoelectric micromirrors. The model addresses both geometric nonlinearities caused by large rotation amplitudes and the nonlinear response of piezoelectric films upon the applic
