Expérimental et théorique
The main objective of the internship is to understand the physics of “acoustic sensing” with a bubble, i.e. using a bubble to detect the presence of nearby materials and measure their elasticity. In a first step we propose to design a 3D cage to hold bubbles that are suited for a local measurement of the surroundings, by monitoring the vibration properties of bubbles. In a second step we will develop the theoretical and experimental tools to detect the presence of solid boundaries, and also to probe the elasticity of the solid. In a last step, we will elaborate on the interaction of multiple bubbles, and how the environment modifies the collective properties.
