When engineering helps improve healthcare

Editorial.   Tomorrow’s medicine will be at least 4P: personalized, preventive, predictive, participative. ‘At least,’ because some would readily add “precise,” “proof” (evidence-based), “pathway-based” etc. Beyond naming this type of medicine and determining the correct number of Ps, medicine is clearly undergoing a profound change. A transformation supported in part by engineering, which is bringing […]

Aerosol therapy: An ex vivo model of lungs

A researcher in Health Engineering at Mines Saint-Étienne, Jérémie Pourchez, and his colleagues at the Saint-Étienne University Hospital, have developed an ex vivo model of lungs to help improve medical aerosol therapy devices. An advantage of this technology is that scientists can study inhalation therapy whilst limiting the amount of animal testing that they use. […]

Bone implants to stimulate bone regeneration

Mines Saint-Étienne’s Centre for Biomedical and Healthcare Engineering (CIS) seeks to improve healthcare through innovations in engineering. David Marchat, a materials researcher at CIS, is working on developing calcium phosphate-based biomaterials. Due to their ability to interact with living organisms, these bone implants can help regenerate bones.   This article is part of our dossier […]

An autonomous contact lens to improve human vision

Two teams from IMT Atlantique and Mines Saint-Étienne have developed an autonomous contact lens which is powered by an integrated flexible micro-battery. This invention is a world first that opens new health prospects, whilst also opening the door for scientists to develop other human-machine interfaces.

Data brokers: the middlemen running the markets

Over the past 5 years, major digital technology stakeholders have boosted the data broker business. These middlemen collect and combine masses of traces that consumers leave online. They then offer them to the companies of their choice in exchange for income. Above all, they use this capital to manipulate markets around the world. These new […]

What happens to nanoparticles when they become waste?

For the past twenty years, industry sectors across the board have been producing a wide range of nanomaterials. They have developed rapidly and with little in the way of regulation. This has led to a regulatory vacuum when it comes to the end-of-life management of these nanomaterials. Little is known about the environmental and health […]

ALGIMEL, a ‘marine’ polystyrene

In the future, materials will not only need to be more efficient; it will also be essential that they are environmentally friendly. With this in mind, researchers from IMT Mines Alès who specialize in bio-sourced materials are working on this project.  Over the past few decades, they have been trying to develop environmentally-friendly alternatives to […]

When plants help us fight pollution

To help reduce or stabilize soil and water pollution, plants provide a rather effective yet inexpensive solution. They must be implemented on a case-by-case basis and could be used in a wide variety of sites.   According to the French Environment and Energy Management Agency (Ademe), 300,000 to 400,000 industrial or mining sites in France […]

Polybioskin, natural skin through more ethical products

Skin contact products, whether for medical, sanitary or cosmetic purposes, have two major drawbacks: they are neither recyclable nor biodegradable. The Polybioskin H2020 project aims to correct these aspects which are out of step with consumers’ growing environmental awareness and concerns. Launched two years ago, the Polybioskin project brings together 12 European partners, including IMT […]

Romain Quey, all about polycrystals

A recent winner of a CNRS Bronze medal, Romain Quey is a materials science researcher at the Georges Friedel[1] laboratory at Mines Saint-Étienne. He focuses especially on the deformation of metallic polycrystalline materials. In the following interview for I’MTech, he presents his research, between synchrotron radiation and digital simulation.     Could you define what […]
