5G & 6G: the antennas that shape networks

,
In a context of constantly growing needs for data transmission, 5G and 6G networks must comply with increasingly strict technical obligations in terms of flexibility, miniaturization, and energy optimization. Solutions explored by researchers include optimal management of radiation patterns and the development of concrete applications for millimeter wave frequencies. Two projects, YACARI and PIIEC ME/CT, are tackling the technical obstacles to these approaches by combining different antenna technologies.

PERSEUS makes a breakthrough for cell-free networks

,
Despite all the promises of 5G, current networks are struggling to ensure seamless connectivity in dense or complex environments. To tackle this problem, the PERSEUS project is developing solutions for cell-free networks in which distributed antenna work together to provide a more fluid service. Based on technologies such as distributed MIMO and new-generation waveforms, the IMT Atlantique research teams involved in the project are trying to solve the technical challenges posed by this new approach.

The Cybaile Chair, securing AI tools for healthcare

,
Thanks to AI tools, it is now possible to identify signs of disease in medical images in a robust and secure way. However, developing such tools requires access to large volumes of sensitive health data. How can we protect this data, and the tools that use it? These are the questions that Cybaile, the industrial chair in cybersecurity, AI and trust in healthcare, is trying to answer.

Omni: observing sustainable digital practices in the workplace

, ,
Businesses can no longer ignore the impact that the digital world is having on the environment. At IMT Atlantique, François Deltour and Virginie Lethiais are using the OMNI observatory to explore initiatives rolled out at establishments in Brittany to reduce their digital footprint. Their latest analyses showcase various practices, ranging from raising awareness to more structured measures such as implementing electronic waste reduction policies or purchasing equipment that has been certified with eco-labels.

Elsa Dupraz, 2024 IMT-Academy of Science Young Scientist Prize

, ,
Channel coding is the focus of Elsa Dupraz's research, a key process for improving information transmission in telecommunications. While the technique’s effectiveness in this field is well known, the researcher is also exploring novel applications, such as data compression and DNA storage. Her research, at the intersection between several disciplines, has fostered multiple collaborations and earned her the 2024 IMT-Academy of Science Young Scientist Prize.

Fabulous laser microstructures

, ,
IMT Atlantique has developed expertise in parallel photoplotting over many years. The school has therefore taken a leading role in the European FABulous project that will use this method to design functional 3D micro and nano-structures. These high-performance optical and photonic microstructures have applications ranging from the automotive industry to biological cell culture.

CEREBRO: towards complete non-invasive imaging of brain activity

, , ,
The aim of the European CEREBRO project is to create the first electrical contrast medium to provide complete non-invasive images of the brain. Current methods for imaging brain activity using electroencephalography are limited in terms of spatial resolution, and do not cover the whole brain. The product to be developed by CEREBRO is designed to overcome these limitations. IMT Atlantique researchers Adrien Merlini and François Rousseau reveal the details of this project.

When assembly lines become circular

, ,
The recycling market is expanding, even to assembly plants! Using a software ecosystem, the European ALICIA project aims to promote the circulation of production resources. Scientists from IMT Atlantique involved in the project are working to develop a platform to optimize production lines, by minimizing machine changeovers and promoting the use of second-hand resources.

Mental disorders: when data helps save lives

,
For several years now, a team from IMT Atlantique has been working in cooperation with doctors from Brest University Hospital and a psychologist from Fondation Bon Sauveur in Bégard to improve early detection of mental disorders such as schizophrenia and to reduce suicidal relapses. The success of this approach based on digital tools lies in the robustness of the analysis and decision models the scientists have developed. It is also dependent on the quality of the health data, which must be correctly recorded by hospital staff.

Good RESOH-lutions for nuclear power

,
The RESOH Chair’s mission is to address safety and performance issues from a socio-organizational perspective. For its third term, the Chair will have a special focus on the issue of skills and facilitating the use of research results by its partners. This research and teaching project led by IMT Atlantique closely analyzes work activities and the dynamics surrounding “safe performance” in high-risk industries, particularly the nuclear sector.
