Project Experience

  • Ph.D. Thesis: 3-D Biomimetic Hair-Like Low-Noise High-Sensitivity Multi-Axis MEMS Accelerometer and Arrayed Accelerometer/Transducer Platform (on-going)
    •  Microelectromechanical (MEMS) Accelerometer DesignModeled in COMSOL Multiphysics a novel design of 3D biomimetic hair-like MEMS accelerometer. Optimized the design of the capacitive accelerometer to achieve sub-µg (<1µg/vHz) low-noise high-sensitivity (>0.1pF/g/mm2) capacitive accelerometer. Validated the FEA simulation results by analytical derivations and experimental testing of in-house microfabricated accelerometer chips
    •  Accelerometer Readout and TestingTapeout front-end IC (switched-capacitor SC charge integrator) in TSMC 180nm technology for high-resolution capacitive accelerometer readout. Performed electromechanical characterization on 1) shaker table AC testing from 0.1g to 30g over a wide frequency range, and 2) optical dividing head for -1g to +1g low-level DC acceleration testing.
    •  High-Yield Microfabrication Technology Development and Cleanroom Experience: Developed a CMOS-compatible high-yield microfabrication process. Gained extensive cleanroom experience in silicon and metal processing. Achieved in-depth knowledge of microfabrication principles and tool operations in cleanroom.
  •  EECS 413 Monolithic Amplifier Circuits (group): Operational Amplifier Using Nested Miller Compensation
    •  Designed, simulated and layout an operational amplifier with 2.13MHz GBW by using nested miller compensation (NMC), a feedforward transconductance stage and a nulling resistor
  •  EECS 514 Advanced MEMS (group): Implantable Piezoelectric Energy Harvester from Lung Motion
    •  Designed and modeled a biocompatible PVDF microfiber reticulate structure to harvest energy from lung motion that operates at low frequency (1-2 Hz) and delivers nW of power.
  •  EECS 515 Integrated Microsystems (group): A Smart Drug Delivery System with Spatial and Temporal Control of Drug Release to Prevent Restenosis in Coronary Stents
    •  Designed a smart drug delivery system on flexible PCB attached to stent with MEMS sensor feedback to deliver anti-proliferation drugs to  locations where restenosis begins
    •  Modeled an electrostatically actuated Polypyrrole valve for controlled drug release through aperture
    •  Studied and simulated by COMSOL a switch-mode polyimide pressure sensor to detect plaque growth
  •  Graphical User Interface for Radioactive Material Detection (Fall 2011)
    •  Acquired and analyzed data preprocessed by FPGA that contained information on the gamma rays and neutron component of radioactive materials from PCI interface
    •  Created GUI to display the properties of the materials, using C++
  •  Characterization of Ink-jet Printing for Wafer Bonding/Sealing of a Miniature Gas Micropump (Summer 2010)
    •  Identified appropriate sealant on various substrates, aligned and deposited the sealing polymer onto specific pattern
    •  Developed the ink-jet printing technique for a sealing polymer (SU8-based) on Dimatix Inkjet Printer
    •  Tested the effectiveness of the new sealing methods using SEM and etc.
