[PODCAST] Quand les algorithmes aident les personnes diabétiques dans leur vie quotidienne 📊 Découvrez le podcast réalisé par Le Réseau des Carnot, qui aborde l’importance de la personnalisation des modèles statistiques pour mieux correspondre au modèle métabolique du patient. 📈 Le taux de glycémie est très variable car une multitude de facteurs peuvent entrer en considération. Un même repas selon l'heure de la journée, le stress ou la fatigue, ne résultera jamais d'un même taux de glycémie. « C’est une fatigue et une charge mentale à long terme » nous rappelle Maeva DORON, ingénieure chercheuse au CEA-Leti et lauréate du prix Carnot de la recherche partenariale soutenant la création d’une entreprise. Maeva a travaillé sur une technologie de pancréas artificiel pour alléger cette charge mentale. « C’est un projet réalisé en étroite collaboration entre le Fonds Santé Diabète - CERITD, Diabeloop et le CEA-Leti. […] qui permettrait un contrôle de l’injection d’insuline, plus fin, plus fréquent, afin de maintenir la glycémie dans les meilleures limites possibles. » 🎧 Retrouvez toute l’histoire de ce projet : https://lnkd.in/e9NS8W8n #carrière #startup #innovation #diabète  François MICELI | Erik Huneker | Pierre-Yves Benhamou | Maïa Sallier | Hélène Loriot | Aurélie Tapini | Diane VINET

[NEWS] Innovative sensors to improve ultrasound scans. CEA-Leti is working on new miniaturized ultrasound #sensors that could lead to smaller, more portable ultrasonic system. How does it work? 🤔 👉 cMUT (capacitive micromachined ultrasonic transducer) and pMUT (miniaturized piezoelectric, micromachined ultrasound transducers) sensors are miniaturized, low-cost ultrasound transmitters/receivers capable of operating across several frequencies. Their microscopic membranes vibrate between 1 and 30 MHZ to create an ultrasonic wave which travels through a liquid and reflects back from the biological object to be analyzed. 🗨 "With these miniaturized ultrasound sensors, we can imagine greatly improve patient monitoring and management thanks to a patch-sized ultrasonic probe.” Bruno Fain, research engineer To learn more about this technology: https://lnkd.in/ejiD6b7b Bruno Fain | Luca Perniola | BARBIER Sandra | Nadège Nief #health #innovation #imaging

[AWARD] Congratulations to Auriane Despax-Ferreres for earning an award at EMPC conference! 👏 Currently, electronic compound interconnections rely on rigid metal brazing. This limits flexibility and recyclability. 🦎🔬 Inspired by the incredible adhesive power of gecko setae, she developed a new biomimetic approach during her thesis. By designing innovative surface microstructures, she created a flexible, stretchable, and detachable conductive adhesive. This groundbreaking solution opens doors for a new generation of electronic devices, from wearable tech to more recyclable electronics compounds. 🎤 Auriane's advice for future researchers: "𝑴𝒚 𝒂𝒅𝒗𝒊𝒄𝒆 𝒇𝒐𝒓 𝒇𝒖𝒕𝒖𝒓𝒆 𝑷𝒉𝑫 𝒔𝒕𝒖𝒅𝒆𝒏𝒕𝒔?

[AWARD] Congratulations to Lou Denaix and Frédéric Barbier for their ICNS-14 awards! 👏 Lou and Frédéric are devoting their research to improving components that will shape the #LED technologies of tomorrow. Their groundbreaking work is light years ahead of the Cathode-ray tube monitors some may remember from childhood. 📺 ☄ Lou's research focuses on improving the manufacture of ultraviolet (UV) and visible-emitting LEDs based on III-N semiconductor materials: aluminum nitride (AlN), gallium nitride (GaN), indium nitride (InN) and alloys of these materials. This #technology has a wide range of applications, including medical sterilization, food processing and UV water purification. “Presenting my research in Fukuoka, Japan, was a fulfilling experience for several reasons. But one of the highlights of the conference was without a doubt my chance encounter with a samurai.” Said Lou 🚨The production of pure red light by LEDs is challenging due to material degradation caused by the high concentration of Indium required. To address this issue, Frédéric and his team have developed a new relaxed InGaN substrate that allows for better Indium incorporation and therefore higher efficiency. “Participating in a conference that specializes in nitrides and presenting the findings of my team were already quite an experience. Because our materials are innovative, having the chance to talk about our findings among nitride colleagues was very rewarding!” added Frédéric ⏩ While Lou will continue to contribute to the understanding of the electrostatic properties of III-N #semiconductors and the use of delta doping to improve its reproducibility, Frédéric is eager to improve the efficiency of red LEDs.

[NEWS] Blood pressure monitoring without the doctor’s office 💗 Hypertension impacts 1.28 billion people worldwide and is a major cause of premature death worldwide. To monitor patients on a continuous basis, CEA-Leti is developing a wearable device to measure blood pressure without needing the inflatable cuff used by current blood pressure monitors. Today, doctors generally examine patients suffering from hypertension once a month. With this patent-protected device, health professionals hope to continuously and remotely monitor blood pressure in order to detect anomalies and be alerted in case of an emergency. 🗨 “With precise blood pressure measurements, we hope to facilitate the monitoring of hypertension and its associated illnesses: heart attacks, strokes and irreversible kidney damage. Currently, 80% of patients worldwide are not properly treated.” Pierre Blandin, head of CEA-Leti's Medical Devices strategic program More info: https://lnkd.in/eC5NzHFh Sophie Morales | Olivier Fuchs | Nadège Nief | Jeremie Pescatore | Arnaud Witomski | Aude Alix #Health #device

[REPORT] Record mmW radar performance to support remote contactless vital sign detection. 💗 CEA-Leti developed a new #radar technology that could enable low-power, high-performance on-chip radar transceivers for the contactless measurement of vital signs for automotive in-cabin systems and #medical devices. The #technology is sensitive enough to generate a human heartbeat profile from surface micro-vibrations of the thorax. ✅ CEA-Leti's teams obtained chirp modulation rates as high as 30 GHz/µs on a 60 GHz carrier, with exceptional phase noise #performance. This is the steepest chirp slope known for mmW radar systems to date. The low-frequency input enables the use of a direct digital synthesizer to perform fast chirping on mmW frequencies. The application-level demonstration of ranging sensitivity confirmed 10 µm sensitivity in the range direction at sensor rates up to 100 kHz—on par with an echocardiograph—even in the presence of significant mechanical disturbances, like those present around a person riding in a car or running on a treadmill. Parasitic movements can be digitally filtered out, leaving clear, accurate vital sign readings.

[AWARD] Integrity and #confidentiality of embedded neural networks – Tackling security threats in the physical dimension ⚡ Congratulations to Kévin Hector for his Best Paper award at the SECAI workshop! 🐱💻 One of the major trends in #AI today is the massive deployment of neural networks on a multitude of embedded platforms. However, #security is one of the major obstacles to the deployment of such systems. Kevin's research project therefore aims to study the so-called "physical" vulnerabilities of neural networks embedded on microcontrollers. 👨🎓 In his final year at ESTIA Institute of technology , Kevin specialized in robotics and embedded systems, obtaining a double degree from the University of Salford-Manchester. Thanks to this experience, he then began a thesis in the "Systèmes et Architectures Sécurisées" (SAS) team, a joint research team between CEA-Leti and the École des Mines de Saint-Étienne. “When we talk about #cybersecurity, the stereotype of an attacker remotely hacking a computer system immediately springs to mind. However, our expertise focuses on a less well-known aspect of IA: hardware security. We work directly at the physical level, interacting with microelectronic components to protect embedded information systems against these forms of attack, which in the past have not been given adequate consideration.” ✅ Kevin identified how some attackers were able to steal information internal to neural networks deployed on microcontrollers by injecting laser faults. Using this method, they were able to illicitly determine some of the targeted neural network’s internal parameters (approximately 80% of their constituent bits). This information was then used to train a substitute neural network that mimicked the targeted network’s performance.
