Switching and Release Dynamics of an Electrostatically Actuated MEMS Switch under the influence of Squeeze-film Damping

Shekhar S., Vinoy K.J., Ananthasuresh G.K., Indian Institute of Science, IN

This paper reports analytical modeling, simulation and experimental validation for switching and release times of an electrostatically actuated micromachined switch. Presented work is an extension of our earlier work [1] that analytically argued, and numerically [...]

Continuous Optimization Method for the Sequence Design of Protein Models Consisting of Multiple Monomer Types

Koh S.K., Ananthasuresh G.K., Yang X., Saven J., Indian Institute of Science, IN

In our earlier work, we had introduced continuous modeling of two discrete states (H: Hydrophobic; P: Polar) of the amino acid monomers and presented a deterministic continuous optimization method to design the sequence that minimizes [...]

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 [...]

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 [...]

The Effect of Thermal Boundary Conditions and Scaling on Electro-Thermal-Compliant Micro Devices

Mankame N., Ananthasuresh G.K., University of Pennsylvania, US

Electro-thermal micro actuators that operate by virtue of constrained thermal expansion induced by Joule heating, have recently received considerable attention. We use electro-thermal actuation to create monolithic compliant devices with embedded actuation in which the [...]

Vision-based Extraction of Geometry and Forces from Fabricated Micro Devices

Wang X., Ananthasuresh G.K., Ostrowski J.P., University of Pennsylvania, US

In the field of micro-electromechanical systems (MEMS), there are often times when a model derived directly from the microstructure of a fabricated device would be useful. In our research, the image of the structure is [...]
