Grenoble startup Enhancia’s connected ring was a hit with international music icon Stevie Wonder, who tried it on at CES Las Vegas. When a musician playing a keyboard or synthesizer wears the ring, it produces additional sound effects according to preconfigured hand movements. “I like it. I love it,” said Wonder. Enhancia’s four founders, all […] >>

Why would a semiconductor material like zinc oxide (ZnO) offer better piezoelectric properties in nanowire form than as a thin film? Researchers at IMEP-LaHC have come up with an explanation. The tip and sides of the nanowire trap the Fermi level, repelling the free carriers in the material, thus eliminating the typical piezoelectric screening effect. […] >>

Bringing high-speed internet access to sparsely-populated rural areas can be a challenge when you only have access to non-contiguous frequency bands—unless you have Leti’s BF-OFDM technology, that is*! Leti just rolled out the technology in Scotland’s Orkney Islands on a test basis, where it was a success. Compared to the OFDM waveforms used in 4G […] >>

Leti showed off its anti-collision-system prototype for drones at CES 2018. The system is the world’s first to provide 360-degree protection from stationary and moving obstacles. Infrared laser sensors detect obstacles, while an algorithm implemented on a commercially-available microcontroller fuses the data and corrects the drone’s trajectory. The complete system weighs in at less than […] >>

A team of researchers from INAC and Institut Néel developed UV and IR photodetectors offering unrivalled performance. The devices are based on a single gallium nitride nanowire. The first, which detects UV B rays, is three times more responsive than the current state of the art. The second can detect IR rays in 100 femtoseconds […] >>
