Actuation Technique for Miniature Robots Developed using Multiphysics Simulation

P. Lazarou, C. Rotinat
CEA LIST, France

Robotic devices for minimally invasive surgery procedures require flexible tools and careful actuation. But most robotic surgery devices are bulky, expensive, and physically draining for surgeons to operate for long periods of time. At the French Atomic and Alternative Energies Commission (CEA LIST), researchers are investigating miniature phase-change actuators that will reduce the strain placed ...

Meeting High-Speed Communications Energy Demands Through Simulation

S. Lei, R. Enright, R. Frizzell, D. Hernon
Bell Labs, Ireland

The information and communication technology industry needs new energy-efficient devices that can keep up with the explosive growth in data traffic of the last few years. Bell Labs, the research arm of Alcatel-Lucent, is taking the lead in an initiative to reduce the carbon footprint of high-speed communication devices and platforms by investing in new methods for cooling electronics and ...

Simulation Software Brings Big Changes to Cable Industry

M. Bechis
Prysmian, Italy

The design and testing of high-voltage cables for terrestrial and submarine applications is paramount to Prysmian's business model. A fundamental challenge in designing power transmission systems is optimizing the cables so that they can reliably deliver the required steady-state current while remaining at, or preferably below, the maximum permissible operating temperature. Incorporating ...

Patterning Cells with the Flip of a Switch for Bioengineering Applications

Tokyo Electron, TX, USA

Dielectrophoresis (DEP) is a method of patterning cells and particles used in medical, electronics, and energy applications. When an electric field is applied to an array of cells or dielectric particles suspended in a medium, they become polarized, causing movement that reorganizes the particles. This is an efficient way to assemble materials layer by layer at the nanoscale, and is sometimes ...

Gaining Insight into Piezoelectric Materials for Acoustic Streaming

G. Potter
SUNY Albany, NY, USA

Many sensors, such as flow sensors and those used in medical diagnostics, rely on microfluidic devices. However, mixing and pumping fluids becomes challenging because of the small size of these devices. As an alternative to traditional actuation methods, surface acoustic waves (SAWs) can be used to create fluid streaming. Through a collaboration between SUNY Albany and SEMATECH, researchers have ...

Enhancing Transmission Line Performance: Using Simulation to Optimize Design

J. Leman
POWER Engineers, MA, USA

Designing power transmission lines requires accounting for many factors: mechanical stress due to environmental conditions and hardware loads, performance testing, and--of course--electrical analysis. Transmission line hardware contains both insulating and conducting assemblies. One common electrical phenomenon is called corona discharge, which occurs when electric fields near the surfaces of ...

Modeling of Complex Physics Speeds Chip Development

P. Woytowitz
Lam Research Corporation, CA, USA

With technological advancements accelerating so rapidly, more powerful computer chips are needed to meet the high demands of fast-growing industries. Lam Research Corporation manufactures semiconductor devices and equipment used to deposit, etch, and clean material layers laid onto wafers during semiconductor processing. With processes as precise as chemical vapor deposition (CVD), temperature ...

Simulating the Release Mechanism in Drug-Eluting Stents

T. Schauer, I. Guler
Boston Scientific Corporation, MN, USA

Stent insertion through the coronary artery is a common procedure used to treat restricted blood flow to the heart caused by stenosis. Following the procedure, restenosis may occur due to excessive tissue growth around the stent. Researchers at Boston Scientific are using multiphysics simulation to better understand how drug-eluting stents prevent tissue regrowth and further improve their ...

Simulation Helps Improve Atmosphere Revitalization Systems for Manned Spacecraft

J. Knox, R. Coker
NASA Marshall Space Flight Center, AL, USA

To ensure astronaut safety on space missions, it is necessary to routinely revitalize the atmosphere in manned spacecraft. Jim Knox, Rob Coker, and a team of engineers at the NASA Marshall Space Flight Center have developed a water-saving system called an Isothermal Bulk Dessicant (IBD). The IBD is used to collect water from the atmosphere for re-use. It consists of packed beds lined with silica ...

Nanoresonators Get New Tools for Their Characterization

J. Yang, M. Perrin, P. Lalanne
CNRS, France

Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter light and interact with their surrounding environment are not well understood, nor are the electromagnetic ...
