Until now patients wondering whether they have tuberculosis had to wait a full 72 hours before finding out the results of a skin test. A new optical read system developed by Leti under a Lyon-Biopôle project funded by the French government has reduced the waiting time to 18 hours—and waiting time could even be slashed […] >>

Detecting electric arcs in the high-power batteries used in electric vehicles (300 V−400 V, 50 kW−80 kW) is a real challenge, since current and voltage fluctuations tend to interfere with the fleeting signals. However, a team of researchers from Leti, Liten, and GIPSA-Lab may have found the solution in a patented acoustic detection method that […] >>

Leti researchers are getting ready to transfer to industry a new wireless communication system that combines ultra-wideband and RFID technology. The new system can transfer data between a mobile phone and a RFID tag at an impressive rate of 100 Mb/s, while using just a few mW of power. Data are stored locally, so users […] >>

Wireless technology could soon replace the cumbersome cables in airplanes’ safety systems and in cars’ ABS and anti-skid systems thanks to a Leti innovation: a miniature 2-cm antenna for 868 MHz UHF frequencies. Leti researchers are now looking at how this antenna can be used for signal propagation in cars and airplanes. The researchers developed […] >>

Phase-change memory is a type of fast, cheap, and non-volatile memory whose only drawback is its high programming current requirement, which limits miniaturization potential and maximum density. However, Leti researchers have obtained promising results from a new “confined structure” phase-change memory architecture that allows for 50 nm chips—substantially smaller than the 300 nm currently available […] >>
