This high-precision technology is based on an acoustic sensor integrating piezoelectric transducers that propagate acoustic waves in the structure tested. The transducer’s impedance phase spectrum is measured, which allows the observation of frequencies of interest related to the mechanical characteristic being estimated. Data are processed in real time to produce information about the condition of the part being tested.

CEA-Leti's Lipidots® technology is a delivery system for therapeutic agents in the context of targeted therapy. Lipidots® are small lipid droplets that transport and deliver active drug compounds via encapsulation. They can also carry biological molecules such as nucleic acids (mRNA, DNA, siRNA, etc.), or proteins and peptides, which have been attached to their surface.

Tomorrow's microdisplays will have to offer both high resolution and high brightness (100 times brighter than those of today) to meet the growing demand for augmented reality applications. Self-emissive GaN-based technology can now offer such performances; CEA-Leti is developing high-resolution, 10 μm pitch GaN microdisplay technology by patterning high-density μLED arrays and hybridizing them on CMOS circuits using its micro-tube technology.
