Andres Arrieta has been named the winner of the 2021 Emerging Leader Award in Smart Materials and Structures for the article: Topological wave energy harvesting in bistable lattices.


Morphing wing tested in wind tunnel

Most airplane wings use hydraulic motors to change their shape and control their flight. But associate professor Andres Arrieta is investigating a simpler kind of “morphing” wing, using bi-stable structures to switch a wing’s shape and stiffness with a minimum amount of energy.
