Getting Touchy-Feely with Touchscreen Design

Peter Vavaroutsos, Andy Kiernan, Cypress Semiconductor, San Jose, CA

We rely on capacitive touchscreens whenever we interact with a smartphone, MP3 device, or car video screen. Touchscreen designs vary by application, so each stack-up (a touchscreen component) is customized for the intended environment. Engineers at Cypress Semiconductor used COMSOL Multiphysics® to improve their touchscreen designs for a variety of uses and optimize their performance. They also ...

The Thermal Management of Li-ion Battery Packs

Michele Gosso & Antonio Fiumara

Fiat Research Center, Orbassano, Italy

At the Fiat Research Center in Italy, Michele Gosso and Antonio Fiumara are working on the development of providing power for electric and hybrid vehicles. The team must combine individual lithium-ion battery pouch cells into battery packs to generate the 350V needed, while providing the packs with sufficient cooling. At the same time, they want to keep the packs as small and light as ...

Simulation-Led Strategy for Corrosion Prevention

S. Qidwai

Corrosion is a widespread concern costing the US billions of dollars annually. For the Navy, specifically, it is the number one maintenance problem. Therefore, at the Naval Research Laboratory (NRL), researchers are developing a method based on multiphysics simulation that will aid material designers in producing corrosion-resistant materials. Their work aims to provide a better understanding of ...

Making Smart Materials Smarter with Multiphysics Simulation

J. Slaughter
ETREMA Products, IA, USA

Smart materials with magnetostrictive behavior are engineered and incorporated in high-precision devices by the designers and researchers at ETREMA Products, Inc. Terfenol-D, in particular, is a giant magnetostrictive material solely manufactured by ETREMA that exhibits the largest deformation of any alloy in response to an applied magnetic field and is integrated into the core of devices such ...

Developing a New Microreactor for Organic Synthesis Using Microwave Heating

W. Lee, K. Jensen

The chemical reactions used to generate solvents and certain pharmaceuticals rely on organic synthesis, a process of combining individual chemicals that can be accelerated through microwave heating. A microreactor system facilitates the direct, localized, and efficient temperature change necessary for successful synthesis. However, a uniform temperature distribution is crucial to the chemical ...

Battling Corrosion in Nuclear Waste Storage Facilities

G. Barbella, P. Geraldini
Sogin, Italy

Nuclear sites in Italy are being decommissioned, leaving questions about how to safely manage and store radioactive waste. Nuclear waste can be stored temporarily in steel drums encased in concrete, but environmental factors must be carefully controlled to prevent corrosion of the steel. It is difficult to constantly monitor the corrosion process, and the relative humidity in the storage area ...

Keeping Cool: SRON Develops Thermal Calibration System for Deep-Space Telescope

C. de Jonge
SRON, Netherlands

Deep-space telescopes require ultrasensitive detectors and calibration to pick up weak far-infrared signals. The SpicA Far-InfraRed Instrument (SAFARI), an infrared camera that will fly aboard the Space Infrared Telescope for Cosmology and Astrophysics (SPICA), has sensors that measure the far-infrared spectrum. The SAFARI system includes a radiation source, needed for calibration, that is so ...

Using Multiphysics Simulation to Prevent Building Damage

P. Sekki
Vahanen Group, Finland

In addition to surviving normal winters, a strong building must be able to survive the worst winters expected in a 50-year period. When moisture and contaminants enter concrete foundations, they create the risk of cracking or other structural damage once the soil or foundation freezes. Vahanen Group specializes in building services and performs quality and risk assessments to make sure that ...

Simulation Turns Up the Heat and Energy Efficiency at Whirlpool Corporation

N. Garcia-Polanco
Whirlpool Corporation, Italy

Engineers working on a joint research project between Whirlpool Corporation and the European initiative GREENKITCHEN project are using simulation to improve the energy efficiency of domestic ovens. Since only ten to twelve percent of the total energy expended by an oven is actually used to heat the food, the researchers had plenty to investigate. Using COMSOL Multiphysics® software and the Heat ...

Simulation Enables the Next Generation of Power Transformers and Shunt Reactors

L. Jovelli
Siemens, Brazil

From power generation to its distribution to end users, power transformers and shunt reactors are used throughout the electrical grid for voltage conversion and to absorb reactive power. At Siemens Brazil in Jundiai, São Paulo, designers are using multiphysics simulation to verify that grid-integrated transformers and shunt reactors can handle increasing power demands without overheating in ...
