摘要：MicroElectroMechanical Systems (MEMS) have become a commercial reality and are readily found in many electronic systems enabling unique signal processing and sensing functionalities in a small form factor. MEMS and their nano version, known as NanoElectroMechanical Systems (NEMS), would have greater transformative impact on the electronic industry if used in large arrays and directly or heterogeneously integrated with CMOS electronics. Large scale integration (LSI) of mechanical components will enable completely new functionalities such as programmability and in-field reconfigurability, paralleling what field programmable gate array (FPGA) have provided to circuit designers.
This talk presents ongoing efforts in 1) the development of piezoelectric MEMS resonator arrays for the implementation of programmable multi-frequency oscillators and filters and 2) the development of piezoelectric NEMS relays for the synthesis of ultra-low power memories and programmable logic. LSI allows us to gain access to individually addressable resonators that can be programmed to synthesize filters and oscillators that hop through different frequencies and bands. Novel and highly scalable piezoelectric NEMS relay topologies providing very low leakage and milliVolt switching will also be shown. These devices result in drastic energy savings and will enable, for example, distributed sensing functionalities that are not yet possible.
报告人简介：Gianluca Piazza is an Associate Professor in the Department of Electrical and Computer Engineering at Carnegie Mellon University. He also holds a courtesy appointment in Mechanical Engineering. Prior to joining CMU he was the Wilf Family Term Assistant Professor in the department of Electrical and Systems Engineering at the University of Pennsylvania. His research interests focus on piezoelectric micro and nano electromechanicalsystems (M/NEMS) for RF wireless communication, chemical/biological detection, and all mechanical computing. He also has a general interest in the areas of micro/nano fabrication techniques and integration of micro/nano devices with state-of-the-art electronics. He received his Ph.D. degree from the University of California, Berkeley in 2005. He has more than 10 years of experience working with piezoelectric materials and devices. He holds several patents in the field of micromechanical resonators some of which have been acquired by industry. He received the IBM Young Faculty Award in 2006 and has won, with his students, the Best Paper Award at the IEEE Frequency Control Symposium in 2008, 2009, 2011 and 2013, and at the IEEE Ultrasonic Symposium in 2012. He serves as an associate editor for the IEEE Journal of MicroElectroMechanical Systems (JMEMS).
