An Online Mems Design Tool That Lays Out and Simulates a Parameterized Array from a Reference Device

Marepalli P., Clark J.V., Purdue University, US

We present an online MEMS design tool that lays out and simulates a parameterized array from a reference device. These automated features are implemented in our tool called SugarCube, which is readily available on nanoHUB.org. [...]

A Systems Design Framework Based in Matlab That Integrates Sugar, Spice, Simulink, Fea Comsol, and GDS-II Layout

Marepalli P., Clark J.V., Purdue University, US

We present a systems design framework called iSUGAR that integrates SUGAR, SPICE, SIMULINK, FEA COMSOL, and GDS-II layout. SUGAR is known for its ease and speed of complex MEMS configuration and parameterization; SPICE is known [...]

Simplifying the Designing of a MEMS-based Nanoscale Material Testing Device

Bansal R., Clark J.V., Purdue University, US

Microelectromechanical-systems (MEMS) are increasingly used for accurate mechanical characterization of nanostructures. However, the performance of such systems highly depends on their structural design. Optimizing the performance of the device using distributed analysis is computationally expensive, [...]

Lumped Modeling of Carbon Nanotubes for M/NEMS Simulation

Bansal R., Clark J.V., Purdue University, US

The construction and analysis of the CNT structure is extremely difficult and requires expertise in nanostructure physics. This limits access to molecular dynamics specialists and does not allow the exploration of CNTs as components of [...]

SUGARX: A Online Tool That Bridges the Gap Between Experiment and Simulation

Marepalli P., Li F., Clark J.V., Purdue University, US

We present a pioneering online tool called SugarX that, for the first time, bridges the gap between experiment and simulation. Our tool is available online at nanoHUB.org with remote experimental control and simulation. A web [...]

Calibrating the AFM with Self-Calibratable MEMS: A Theoretical Study

Li F., Clark J.V., Purdue University, US

To perform reliable scientific measurements with the atomic force microscope (AFM), it is important to calibrate the AFM cantilever. Conventional calibration methods have a 10 to 15% uncertainty, and the accuracies of such methods are [...]

Gravimeter on a Chip: A Theoretical Study

Li F., Clark J.V., Purdue University, US

We present a theoretical study of our proposed gravimeter on a chip. A gravimeter is a device used to measure gravity. In contrast to conventional gravimeters, our gravimeter is expected to be microscale, cheaper, more [...]

SugarCube: An Online Tool for Investigating the Performance of Ready-Made Parameterized MEMS

Marepalli P., Clark J.V., Purdue University, US

We present an online tool - SugarCube which facilitates the parameterization of ready-made MEMS. Using this tool one can investigate the performance of parameterized MEMS which are available in the form of hierarchical libraries. This [...]

Improved Modeling of the Comb Drive Levitation Effect

Li F., Clark J.V., Purdue University, US

Lumped comb drive models found in the literature ignore the electrostatic levitation effect, which decreases their accuracy. The levitation effect occurs when the substrate is within close proximity to the comb drive. This common configuration [...]

An Online Electrostatics Modeling Tool for Microdevices with Dirichlet Boundary Conditions by Schwarz-Christoffel Mapping

Li F., Clark J.V., Purdue University, US

We present an online software tool that quickly and accurately models and simulates the electrostatic properties, such as capacitance, charge distribution, and electrostatic force, of microdevices in 2.5D domain with Dirichlet boundary conditions by using [...]
