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.
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.
Energy harvesting – creating electrical energy from cars driving over a road, or people walking on a bridge – has long been theorized as a potential source of sustainable electricity. But due to the physical properties of those vibrations, implementing the process has been largely infeasible. Now, Andres Arrieta has proposed using metamaterials as physical frequency converters, potentially bringing us a step closer to harvesting the energy of those vibrations.
When you press the dimpled circles on a fountain drink lid, they become either convex or concave. This demonstrates bistability: materials or structures that have two stable states. Prof. Andres Arrieta has demonstrated a patterned sheet of these domes that forms an energy-storing skin, strong enough to perform mechanical tasks, and even programmable to store and process data like a mechanical computer.
"Flat pack furniture" may soon have a new meaning. Purdue researchers have developed a 3D printing method that emulates the switchable bistability of the Venus flytrap plant. This breakthrough in material science may soon inspire flat objects that snap into their final stable form with very little external force.
Andres Arrieta has received the CAREER award from the National Science Foundation, their most prestigious award in support of early-career faculty. His project is "The Mechanics of Hierarchically Multistable Metastructures."
