Abstract
Piezoelectric energy harvesters (PEHs) are widely studied for powering low‑energy electronics and enabling remote sensing technologies. While existing models accurately describe underlying physics, real‑world performance is often affected by uncertainties in electromechanical properties and geometric characteristics. These uncertainties can significantly influence device reliability and make it challenging to achieve consistent performance in practical applications.
In this webinar, Dr. Ruiz will review recent advances in Uncertainty Quantification (UQ) for PEHs, including methods to characterize and propagate uncertainty in material properties and geometry. The talk will highlight the use of Bayesian inference to update electromechanical properties using experimental data, as well as design and optimization strategies based on surrogate models. The presentation will also discuss emerging piezoelectric‑based metamaterials designed for both vibration suppression and energy harvesting, with attention to accounting for geometric uncertainty from additive manufacturing within a robust UQ framework.
Speaker Bio
Dr. Rafael O. Ruiz joined the University of Michigan–Dearborn in 2022 after nearly six years as a faculty member at the University of Chile. He earned a dual Ph.D. from the University of Notre Dame and the Pontifical Catholic University of Chile. His research focuses on vibration control, multifunctional metamaterials, and piezoelectric energy harvesters using stochastic simulations and surrogate modeling.
