Carlos De Marqui Junior

As the PI, Carlos De Marqui Junior coordinates and organize the local staff at EESC/USP to support the research team in all required tasks (scientific and administrative).

The PI also actively participates in the research activities, mainly the ones related to WP#3 and WP#4 of this proposal. The research group coordinated by the PI at the Department of Aeronautical Engineering of EESC/USP has experience in smart materials and structures, vibrations control, modeling and experiments on linear and nonlinear electromechanically coupled systems, metamaterials, vibration based energy harvesting, and aeroelasticity.

The PI coordinates research to develop new nonlinear piezoelectric metamaterials through the development of new self-powered nonlinear electrical circuits (nonlinear energy sink, polynomial nonlinearities, bistable circuits, time/space modulated systems for nonreciprocal wave propagation) for enhanced performance, multifuncionatlity (EH, damping, SHM, sensing), and tunability (through the online modification of digital circuits parameters).

Numerical modeling and experimental validations are also carried out. Moreover, a new class of nonlinear metamaterials based on shape memory alloys has been developed for enhanced damping (due to pseudoelasticity) and tunability (through the active control of SMA elements stiffness), numerically investigated and experimentally validated. Applications include vibrations control, energy harvesting and aeroelasticity.

The research group includes:
