Discovery Park Undergraduate Research Internship Program

"Aerodynamic Damping in MEMS Accelerometers"

About the Project

Project Time & Type:
Fall 2011 - DURI
Research area(s):
Nano/Microsystems
Project Description:
Recently there have been efforts for sensing high-g accelerations in the order of 20,000 g - 60,000 g by detecting contact events of silicon microbeams. These high-g events are generally prominent in impact and shock events. The design and failure analysis of microdevices under such events requires accurate modeling of dynamic response. The response time and the overall dynamics are greatly affected by the aerodynamic damping during deflection, particularly in the near-contact regime. The project involves computational modeling of gas damping in MEMS accelerometer using Boltzmann-ESBGK flow solver developed at Purdue.
Expected Student Contributions:
Computational modeling, analysis of data.
