Leti and SYMME* developed a standout piezoelectric energy harvester. The researchers increased bandwidth by an impressive 446% and achieved near-state-of-the-art total efficiency of 94%. The device’s excellent performance can be attributed to a smart interface that dynamically tunes the resonance frequency to the environment’s vibration frequency. This allows the device to harvest energy beyond what […] >>

Researchers at Irig developed an ultra-fast magnetic tunnel junction (MTJ) that could be used to log events captured by stroboscopic photography. They used a terbium-cobalt layer whose magnetization can be switched using a femtosecond laser. A second magnetic layer is made from a material whose magnetization is not switchable. The magnetizations of these two layers […] >>

Creating photonic circuits that leverage Leti’s 310 nm platform just got easier. Mentor Graphics’ Tanner design flow now includes an integrated Process Design Kit (PDK). The PDK provides access to a library of proven components and can also be used to design new ones. It is also fully compatible with another Mentor Graphics tool that […] >>

Researchers at Irig used a transmission electron microscope to observe the behavior of aluminum (Al) heated to temperatures in excess of 250 °C when it comes into contact with a germanium (Ge) nanowire. So, what did they see? Well, the Al propagates in the nanowire along a well-defined front; the Ge is pushed back and […] >>

Silicon Valley startup Innovasonic turned to Leti to develop an innovation the company patented. The technology leverages ultrasonic waves generated by an array of piezoelectric transducers just 100 µm thick (about the same as a human hair) to clean transparent surfaces. The waves are uncannily effective at removing water droplets and grime. The technology is […] >>
