Modeling Scar Effects in Electrical Spinal Cord Stimulation

Kris Carlson, Dr. Jay Shils & Dr. Jeffrey Arle
Lahey Clinic
Burlington, MA

The Neuromodulation Group at Lahey Clinic conducted a study based upon spinal cord stimulation (SCS). SCS involves implanting a series of electrodes that apply electric potential to the spine, interfering with pain signaling circuitry. It’s used to alleviate chronic back and leg pain. Although the treatment remains effective for years, the electrodes must be reprogrammed through trial and ...

Multiphysics Simulations Enable Development of Fast, Cheap MEMS-Based Bacteria Detector

Yale University
New Haven, CT

Professor Mark Reed and his team at Yale University are using COMSOL Multiphysics to develop a MEMS-based solution for detecting bacteria in blood. Called the aScreen, it will provide analyses speedily, accurately, and cost-effectively. Such a device would greatly help the food industry in improving meat quality and reducing the risk for infections. Current methods take too long for most food ...

Floating on Sound Waves with Acoustic Levitation

K. Suthar, C. Benmore
Argonne, IL, USA

As part of an industry that saves lives on a regular basis, pharmaceutical companies are in need of systems that can be used to deliver high-quality medicines. One method utilizes sound waves generated by an acoustic levitator with foam-coated transducers. Using the acoustic force from the sound waves, chemical particles are suspended between the transducers, where they can be mixed in a ...

Control of Joule Heating Extends Performance and Device Life

Jean-Louis Gelet and Antoine Gerlaud
Mersen, France

Large electrical systems carrying high currents could pose a danger if any of their components, such as fuses and bus bars, fail. In order to increase safety and improve manufacturing, it is necessary to understand the failure mechanisms of those components. One of those components, a bus bar, is made up of a single piece of conducting metal that replaces individual, thick cables when conducting ...

Tianjin Institute of Power Sources, Tianjin, China

Dr. Songrui Wang is a researcher at The Tianjin Institute of Power Sources, involved in battery testing and evaluation for design recommendations on safety. She analyzes the risk of potential fire hazards associated with lithium ion batteries, which are fast becoming the most popular sort of battery for vehicles, mobile devices, and many other applications. COMSOL Multiphysics was used to ...

Switching Made Easy

Matthias Richwin,
Leopold Kostal GmbH,
Dortmund, Germany

Modern cars offer a wide range of complex functionality that comes with several design challenges. This story discusses some of the necessary updates to a roof module in a premium car and the charging system of an electric car. The roof module of a particular model houses several components. 90% of the generated heat goes into its printed circuit board (PCB), so temperature control is vital for ...

The Burning Need for Modeling

Gianluca Argentini
Riello Burners
Legnago, Italy

Riello Burners manufactures high-efficiency low maintenance burners for use in residential and commercial heating applications, as well as in industrial processes. Proper ventilation is crucial for a burner because it maintains appropriate air flow into the combustion head where the flame is located. When designing the fan for any burner, there must be a balance between a configuration which ...

Around the Clock Solar Power

ENEL, Rome, Italy

Italian utility ENEL and the Italian National Agency for New Technologies joined together to develop a new kind of Concentrating Solar Power (CSP), using Parabolic Trough CSP to generate electricity during sunny hours as well as under overcast conditions or at night. This new type of CSP plant depends on molten salt as a medium for storing heat in large, well-insulated tanks. Molten salt has ...

Upgrading the Nuts and Bolts of the Electrical Grid for a New Generation

Göran Eriksson
ABB AB Corporate Research Power Technologies
Västerås, Sweden

Lukas Graber, Mikael Steurer, and Tim Chiocchio
Center for Advanced Power Systems
Florida State University
Tallahassee, FL

Bruker Energy & Supercon Technologies
Billerica, MA

Migrating the electrical grid to a “smart grid” is usually discussed in terms of IT issues or embedded systems. Yet, just as important updating the “nuts and bolts” of the smart grid. At ABB AB Corporate Research Power Technologies in Sweden, scientists are working to reduce line current and the resulting resistive loss in cables caused by the use of increased voltage in modern ...
