Stimuli-responsive materials
To go beyond material characterization, we design functional materials with tailored properties.

FERROMAGNETIC GRAINS
Mickaël Bourgoin, Stéphane Santucci, Nicolas Taberlet
Tuning mechanical & dynamical properties of granular structure and flow is possible using ferromagnetic grains under an external magnetic field. We thus revisit classical granular properties such as the Janssen effect.
PHOTOLUMINESCENT FILMS
Photoluminescent films are developed as novel temperature sensors.
RHEOLOGY UNDER ELECTRIC FIELD OR POWER ULTRASOUND
Thibaut Divoux, Thomas Gibaud, Sébastien Manneville
External stimuli can tune the mechanical properties of gels or foams. This topic explores the response of such materials, with the goal of controling the material flowability or "training" soft solids to enhance their mechanical properties.
