Magneto-active soft materials and structures

TheEuroTech Universities Allianceis a strategic partnership of leading European universities of science and technology:Technical University of Denmark (DTU)École Polytechnique Fédérale de Lausanne (EPFL)Institut Polytechnique de ParisTechnion - Israel Institute of TechnologyEindhoven University of Technology (TU/e)Technical University of Munich (TUM)The universities join forces to build a strong, sustainable, sovereign, and resilient Europe. The partners bring their excellence in research and education, their active engagement in vibrant eco-systems and service to society. Together, they join forces to accelerate their research in high-tech focus areas and advocate for change, through dedicated partners and a strong presence in Brussels.Based on the EuroTech values, the partners aspire to a new level of cooperation by bringing together their inclusive, diverse and sustainable campuses. The EuroTech Universities create a unique environment for international talents to lead a new generation of change agents in research, entrepreneurship, industry and society.

EuroTech Universities Alliance

Tackling global challenges together. A series of scientific online lectures by renowned researchers of EuroTech Universities

EuroTechTalks

The EuroTechTalks are a series of scientific online lectures by renowned researchers of EuroTech Universities. In the Alliance, we tackle global challenges together. This series highlights some outcomes of our scientific collaborations.

In this joint seminar, Prof. Kostas Danas (École Polytechnique) and Prof. Pedro Reis (EPFL) will present the complementary expertise and recent research of their two groups at Ecole Polytechnique (France) and EPFL (Switzerland) on magnetorheological elastomers (MREs); a novel class of active materials capable of exhibiting a coupled response under external magnetic and/or mechanical stimuli. These solids are composites comprising magnetic micron-sized particles embedded randomly in a polymer matrix. MREs can be categorized into soft- and hard-MREs. Soft-MREs are typically made of carbonyl-iron particles and tend to exhibit no magnetic dissipation, while they lose their magnetization when the magnetic field is switched off. Hard-MREs, which are made of permanently magnetizable particles (e.g., NdFeB), are dissipative magnetically and retain a remanent magnetization in the ground state; i.e., they are compliant permanent magnets. In this talk, they will focus on the fabrication, experiments, and modeling of MREs, especially in leveraging their instabilities for function, to deliver configurational and geometrical changes with minimal external magnetic fields. Examples of novel applications related to biomedical devices and soft robots will be discussed.AboutThe EuroTechTalks are a series of scientific online lectures by renowned researchers of EuroTech Universities.
