Microsystem Model Evaluation Using Optimization Strategies

Peters D., Laur R., University of Bremen, DE

This paper presents an automatic approach for evaluating behavioral models of micro systems' components. Optimization methods are applied aiming at the specification of a model's scope of application. The method is presented by evaluating a [...]

Structural Design of Micro Electrostatic Actuator for Optical Memory Using Design Windows Searching Method

Ishihara D., Jeong M.J., Yoshimura S., Yagawa G., Kim Y.J., University of Tokyo, JP

For satisfactory design of micromachines, this paper describes a search method for a multi-dimensional design window (DW), which is defined as an area of satisfactory solutions in a feasible design parameter space. The method consists [...]

Simulation and Optimum Design of Finline/Slotted Line Millimeter Wave Antenna

Fu J.S., Ng C.L., Kwang Y., Sia E.K., Tan S.H., Nanyang Technological University, SG

Simulations are carried out using XFDTD software to determine the set of input values for several parameters of the fin line antenna, to give an optimized radiation performance in the principal planes. A further modification [...]

Design of Reconfigurable Composite Microsystems Based on Hardware/Software Co-design Principles

Zhang T., Chakrabarty K., Fair R.B., Duke University, US

Custom microsystems are expensive, inflexible, and unsuitable for high-volume production. We address this problem by leveraging hardware/software co-design principles to design reconfigurable composite microsystems. We partition the system design parameters into nonreconfigurable and reconfigurable categories. [...]

Computer-Aided Kinematic Design of a Torsional Ratcheting Actuator

Sacks E., Barnes S.M., Purdue University, US

We have developed an interactive computer-aided design program that supports the mechanical design of devices fabricated in surface micro-machining processes. The program automates kinematic analysis via a novel configuration space computation code, performs real-time simulation [...]

Noise Modeling Methodology for Full-System Inertial Microsensor Codesign

Pottenger M.D., Kaiser W.J., University of California at Los Angeles, US

Methos for incorporation noise models into full-system inertial microsensor simulation are presented. Thermal motion of the proof mass and flicker noise in the interface circuit exhibit essential behaviore that must be included in sensor design. [...]

Voxel-Based Heterogeneous Geometric Modeling for Surface Micromachined MEMS

Perrin A., Ananthakrishnan V., Gao F., Sarma R., Ananthasuresh G.K., University of Pennsylvania, 220 S. 33rd Street, US

A heterogeneous geometric modeler for microeletromechanical systmes (MEMS) is the focus of this paper. ON the basis of a comprehensive formalism describe in our earlier work, we present a 3-F implementation of the forward (from [...]

Designing Efficient Computer Experiments for Metamodel Generation

Crary S.B., Woodcock D.M., Hieke A., Crary Group, US

We demonstrate the relative merits of IZ-optimal designs for computer experiments relative to Latin hypercube designs, using two examples, both in two factors and eleven points, one a simple function from Welch et al. [1] [...]

Robust Mask-Layout Synthesis for MEMS

Ma L., Antonsson E.K., California Institute of Technology, US

A method for automated mask-layout and process synthesis for MEMS using Genetic Algorithms was proposed by Ma and Antonsson [5]. For a given desired device shape, and several fabrication process choices, this synthesis method will [...]

A New Material Interpolation Scheme for the Topology Optimization of Thermally Actuated Compliant Micromechanisms

Yin L., Ananthasuresh G.K., University of Pennsylvania, US

Thermally actuated compliant micromechanisms are selectively heated elastic continua that take advantage of nonuniform thermal expansion and mechanical leveraging to amplify displacements and forces. These can be designed systematically, as shown in the earlier work [...]
