The Shanghaitech Microsystem And non-Linear transducers Laboratory (SMALL) is established in Fall 2017 associated with the School of Information Science and Technology at ShanghaiTech University by Principle Investigator Dr. Tao Wu.

At SMALL, we are developing miniature sensor and actuator systems made using advanced materials and micro/nano-fabrication processes. Research in this area is motivated by the potential to produce high-performance, low-cost, miniature sensors and actuators. Specific research areas of interest include Micro-/Nano-Electro-Mechanical System (M/NEMS) design and modeling, nanometer-scale data storage, novel multiferroic materials, processing and transducers, as well as their applications in smart hardware, renewable energy systems, Internet-Of-Things (IOT) etc. The researches at SMALL are, in particular, interdisciplinary, which incorporates the expertise from many engineering and scientific disciplinarians. We welcomes all science and engineering background to join this lab to explore fascinating micro/nano-technologies.

    • We present our work in 2017 IEEE SENSORS Conference!

      Dr. Tao Wu attended and present work titled “Design and Fabrication of AlN RF MEMS Switch For Near-Zero Power RF Wake-Up Receivers” on 2017 IEEE SENSORS Conference held in Glasgow, Scotland, Oct. 30 – Nov. 1, 2017.

      We describe an AlN-based resonant switch (resoswitch) for use in a Near-Zero (NZero) RF Wake-up receiver. A folded beam structure compensates for the curvature
      caused by the stress gradient in sputtered AlN and ensures that the free end of center actuation beam is level with the side anchor beams. A 80.13 kHz resoswitch with Q over 4000 and an actuation gap of approximately 600 nm turns on when a -7 dBm, 800MHz signal square wave modulated at 80.13 kHz is applied to the actuator. This AlN electrostatic resoswitch enables integration of a high gain RF piezoelectric transformer with a high-Q electrostatic resoswitch for an ultra-low power RF receiver.
