How can we best monitor air quality, which is responsible for 4.2 million premature deaths per year worldwild? CEA-Leti is developing a number of sensor technologies, in particular high-performance, low-cost photoacoustic sensors, which would make it possible to increase the number of monitoring devices in the field.
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.
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.
Lou and Frédéric are devoting their research to improving components that will shape the LED technologies of tomorrow. Applications for their work are very different from the Cathode-ray tube monitors some may remember from childhood.
SOLEM and CEA-Leti have joined forces to create a device capable of capturing energy from irrigation water while limiting losses in pressure. SOLEM is now marketing a hydrogenator that can be integrated into its connected irrigation solution.

Currently, interconnection solutions for electronic compounds involving an active side directed at substrates rely on metal brazing. Mechanical contacts are therefore rigid. For better adhesive reliability, a thermosetting resin is generally used as an underfill. This redistributes the thermomechanical constraints produced by differences in thermal expansion coefficients between the silicon chip and the substrate. The remarkable adhesiveness of gecko feet has long fascinated scientists. Their secret lies in a three-level hierarchical structure that supports low-intensity physical interactions, called the Van der Waals force.
Following a risk assessment phase, the European Space Agency (ESA) has announced the launch of the NanoMagSat mission, which aims to map Earth's magnetic field. CEA-Leti is actively involved in this project as it is responsible for developing the on-board magnetometers and the entire payload of the future satellites.
CEA-Leti is working on new miniaturized ultrasound sensors that could lead to smaller, more portable ultrasonic system. This innovative system could be used without gel, for example as a patch.
Integrity and confidentiality of embedded neural networks – Tackling security threats in the physical dimension
In collaboration with Smiths Detection, CEA-Leti developed an innovative detection module for small-angle X-ray diffraction. This module is integrated into a novel type of airport baggage-scanner. The SDX 10060 XDi is marketed by Smiths Detection and had its world premiere at the Passenger Terminal Expo in Frankfurt, Germany, on April 16-18, 2024.
CEA-Leti scientists presented three papers at the IEEE Symposium on VLSI Technology and Circuits detailing the institute's progress on 3D integration technologies, which are a promising approach for designing More than Moore systems, especially radio frequency (RF) integrated systems.
CEA-Leti is proud to announce the kick-off meeting today of the FAMES Pilot Line, a pioneering project aimed at advancing semiconductor technologies in Europe. This 830 M€ initiative aligns with the ambition of the EU Chips Act, which seeks to bolster EU semiconductor capabilities and ensure technological sovereignty.
Companies of all types and sizes—from startups to established corporations—can work with the CEA, leveraging the expertise of both CEA-List and CEA-Leti, to develop next-generation integrated circuits for consumer electronics, automotive systems, medical devices, and other tech-intensive products. Learn how CEA experts are helping companies quickly and efficiently take their product innovations from lab to fab.
Trans-Atlantic Collaboration Starts with Focus on Enabling Next-Gen Magnetic Memory Devices at the 300mm Wafer Scale
In the latest Clarivate ranking of the world's top 100 innovators, CEA is ranked 31st and first among public research organizations. This performance rewards CEA-Leti's policy of promoting innovation and its scientific and economic impact, notably through the filing of patent applications.
The need for reliable methods to ensure the safety and security of Edge artificial intelligence systems has never been more pressing. With regulations like the EU’s AI Act sharpening the collective focus on AI trustworthiness, risk, and acceptability, CEA-Leti made a breakthrough on the often-overlooked physical threats to AI systems, demonstrating a robust evaluation method on a common IoT use case.
The fruitful collaboration between NUVIA and CEA-Leti continues with the development of NuVISION-MAX, a compact gamma camera that significantly improves sensitivity.
Quantum transistors are a promising technology for the future of electronics. They could give rise to computers that are more powerful, more energy-efficient and more secure than classical computers. However, their integration remains a major technological challenge. In order to enable the manufacturing of these new architectures a plasma etching method called atomic layer etching is used.
With years of expertise in silicon photonics, CEA-Leti researchers have developed two complementary approaches for high performance photon detectors. This innovative technology meets the needs of disruptive applications in a variety of sectors such as Free Space Optics for telecoms, quantum computing and quantum cryptography. Depending on application requirements, CEA-Leti now offers cutting-edge solutions using either Avalanche Photodetectors (APD) with Mercury Cadmium Telluride (MCT) or Superconducting Single Photon Detectors (SSPD).
