| Abstract | Over the past three decades, huge progresses have been made in MEMS technologies. Hundreds of millions of MEMS, principally: accelerometers, gyroscopes and microphones, are commercialized yearly. This should continue to increase rapidly with upcoming new applications related to IOT or autonomous cars. These new opportunities could be the trigger for a rapid growth of the MEMS actuators market. To perform micro-actuators, LETI has been developing for more than 25 years a large know-how on piezoelectric thin films: Lead Zirconate Titanate (PZT) and Aluminum Nitride (A1N). Using PZT or A1N thin films deposited by sol-gel method and sputtering respectively on a released silicon membrane, two powerful technological platforms have been developed for a large number of applications. These platforms and some of these applications are presented below. |
