Microvisk Technologies, North Wales, UK
Microvisk Technologies develops and manufactures devices for measuring blood viscosity using the power of Micro Electronic Mechanical Systems (MEMS) and a radical new technique stemming from futuristic research on microtechnology. Older hand-held devices on the market work by inducing a chemical reaction that is picked up by electrodes coated with componds. The MEMS-based micro-cantilever ...
Human activity steals oxygen from natural water sources such as lakes and this oxygen-deficient water often contains high levels of toxic substances such as metals and organic material. Thus the number of lakes that can be used as a source of water is reduced, straining the available resources and creating a need for water-treatment plants of water which can have negative impacts when powered ...

CSEM SA, Neuchatel, Switzerland
CSEM is a private applied research and development center specializing in micro-technology, system engineering, micro-electronics, and communications technologies. One of their latest projects is working on minimizing the weight of satellite attitude control systems as every gram of payload matters when launching a satellite into orbit (€15,000 per kilogram). CSEM hopes to accomplish this task ...

AltaSim Technologies provides engineering consulting services involving advanced multiphysics modeling such as capacitively coupled plasma (CCP). Plasma etching and deposition of thin films, critical processes in the manufacture of advanced microelectronic devices, commonly utilize CCP, in which the plasma is initiated and sustained by an oscillating electric field between two or more ...
CEA, Leti, Minatec, Grenoble, France
CEA-MINATEC is an international center for micro and nano-technologies which is funded by CEA, a French government-funded technological research organization. One of their current projects is developing silicon-based MEMS CO2 sensors that employ optical detection for monitoring adequate building ventilation. For the sensor to function, a filament is heated to a specific temperature so that it ...
A 100-Fold Improvement in Lithography Resolution Realized with a 150-Year-Old “Perfect Imaging” System
Juan Carlos Miñano and Dejan Grabovičkić
Cedint Polytechnic University of Madrid
The idea of "perfect imaging", that is a resolution less than the wavelength of light producing the image, was first proposed in the mid-19th century by famed Scottish physicist James Clerk Maxwell. For the next 150 years, it was widely believed that such was impossible due to the fact that light diffracts around points that are the same size or smaller in wavelength. Then, in 2009, Ulf ...
Cochlear Technology Centre, Mechelen, Belgium
Cochlear Technology Centre Europe (CTCE) develops new technology for hearing implants. Their current work is with a new type of hearing implant, a Direct Acoustic Cochlear Implant called CodacsTM. This product imposes structural, pressure waves directly to the cochlea, stimulating it this way, as opposed to amplifying sound. Using COMSOL Multiphysics, the team was able to test the many ...

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 ...
