Interview of Michaël Baudoin in the monthly magazine Sciences et Avenir – The Research
(n°900, February 2022)
Michaël Baudoin, professor at the University of Lille and researcher at IEMN in the AIMAN-FILMS group (Impulsive Acoustics & Nonlinear Magnetoacoustics - Fluids, Liquid Interfaces & Micro-systems) was interviewed in an article of Sciences et Avenir – La Rechercheon the use of acoustic waves in the levitation of objects.

Extract from "Sound waves make objects levitate", Arnaud Devillard, Sciences et Avenir – The Research n°900, February 2022
Arnaud Devillard, its author, addresses the fascinating subject of making an object move without touching itHandling an object without touching it: this is the promise of acoustic waves that create a vertical thrust capable of counteracting gravity. A fascinating feat achieved in the laboratory that opens the way to non-contact surgery to move, for example, kidney stones without surgery [...]" (excerpt from the article)
The principle of levitation, known since the 1930s, is evolving with the growing role of miniaturization which, as Michaël Baudoin explains, "leads to standing waves at much smaller scales.
Michael's team previously published work on "Acoustic vortices to manipulate and organize individual cellsin Nature Communications in 2020.
