Electro-thermal aspects in carbon based interconnects

Verma R., Bhattacharya S., Mahapatra S., Indian Institute of Science, IN

The tremendous rise in Joule-heating in conventional ICs has led down ITRS to ensure on material alternatives that surpasses break-down current density and thermal conductivity (κ) beyond room temperature (RT). In recent years, suspended metallic [...]

Sacrificial membranes for serial valving in microsystems

Allain M., Berthier J., Basrour S., Pouteau P., CEA/LETI/MINATEC, FR

Valving is essential to microflow circuits in microsystem technology. Many different types of valves have already been designed. Membranes of sacrificial materials have been studied for one shot valving; however, the new design proposed here, [...]

Adaptive temperature estimation in 3D single-cell dielectrophoretic traps using the boundary Element Method

Rosales C., Institute of High Performance Computing, A*STAR, SG

Application of dielectrophoresis techniques to biological particles is limited by the temperature increase of the suspension due to Joule heating. This temperature increase can be obtained from a Poisson equation, but the presence of the [...]

Thermal modeling of a PMMA microfluidic separation chip

Zhu Y., Bui A., CSIRO Australia, AU

The main objective of the current work is to investigate the thermal performance, in particular Joule heating of polymer microfluidic chips involving electrokinetically driven flows using experimental and numerical methods. Most of the work focused [...]

Modeling of Dielectrophoresis for Handling Bioparticles in Microdevices

Yao G.F., Flow Science Inc., US

Dielectrophoresis can be used to trap and position bioparticles efficiently and sucessfully in BioMEMS devices. This paper present a computational model to simulate this process. In particular, the model will solve for electric potential distribution, [...]

Modeling of Joule Heating in Electrophoretic Separation Microchips

Wang Y., Lin Q., Hoburg J.F., Mukherjee T., Carnegie Mellon University, US

This paper presents a model for Joule heating induced analyte dispersion in electrophoretic separation channels with a rectangular cross section. The model is in closed form and captures the effect of cross-sectional geometry. Three-dimensional numerical [...]

Joule Heating Simulation of Poly-Silicon Thermal Micro-Actuators

Silversmith D.J., Reid J.R., Air Force Research Laboratory, US

Previous studies of surface micro-machined polycrystalline silicon MEMS thermal micro-actuators have shown that these simple devices can provide deflections on the order of 10 micrometers at CMOS compatible drive voltages. These thermo-mechanical devices operate by [...]
