RFID systems are inexpensive, but their range is limited, and they are not as accurate as they could be. This makes them unsuitable for tasks like automated inventory tracking with functionalities like people and property location or counting, for example.CEA-Leti, a member of the Carnot Network, developed a miniaturized superdirectional antenna and direction and distance […] >>

Irig’s electronic nose, originally designed for consumer and industrial applications, is now being used in the early detection of diseases.Here’s how it works: some diseases—especially cancer—alter the metabolic production of volatile organic compounds (VOCs), some of which are relevant biomarkers.In this research, which focused on two oeso-gastric cancer biomarkers, record detection limits (around one part […] >>

CEA-Leti developed MEMS micromirrors for automotive LiDAR systems in research conducted for the EU Vizta project.The CEA-Leti micromirrors move on two axes—right to left and top to bottom—, reflecting the laser beam to effectively scan a scene for vehicles, pedestrians, and obstacles.The mirrors are controlled by piezoelectric actuators that slash operating voltage sixfold compared to […] >>

Scientists from Irig, CEA-Leti, and materials science lab C2N recently showed that a germanium-tin alloy microdisk laser cavity can emit at a record temperature of 32 °C. A tin content of 17% and a pedestal-type architecture that enables better dissipation of the heat from the stacked layers made the advance possible.Tin atoms are larger than […] >>

Attendees at Leti Innovation Days in June had the opportunity to see a paraplegic patient walk with crutches. Beyond the wow factor, the video highlighted the encouraging results obtained by the CEA, EPFL*, and startup Onward since 2021.The patient featured had been implanted with two devices: the Clinatec-developed Wimagine brain activity recorder and a spinal-cord […] >>
