Microfluidics Model of an Electroosmotic Micromixer

October 31, 2012

When you need to mix something at a very small scale you don’t reach for a teeny-tiny whisk. If you’re working with microscale biochemical applications you’d be more likely to rely on diffusion to mix fluids. With highly ordered laminar flow there is no turbulence involved, thus making diffusion a prime candidate for “getting the job done”. But what if you need to mix larger molecules? Larger molecules mean higher molecular weight, which in turn leads to very long equilibration […]

New Product that Helps Electrical and Electronics Engineers

October 18, 2012

As much as we would like to think that finite element analysis (FEA) is the be-all and end-all of simulations, it’s not true. There is also a camp of engineers out there that model integrated circuits and similar systems. These are based on different physics and equations than what FEA typically solves for. Yet, as is happening more and more in the world of virtual prototyping, the two types of simulations are converging. Now they need to integrate with each […]

Piezoelectric Energy Harvester Helps Increase a Car’s Efficiency

July 26, 2012

Much has been written lately about increasing the energy efficiency of cars. Batteries and fuel cells are very hot topics, and not so long ago I blogged about the University of Michigan’s use of solar cells to fully power a car. Yet, even on the smallest of scales, such as the sensors in your car, improvements are being made. Utilizing a MEMS (Micro Electromechanical System) piezoelectric energy harvester, Alexander Frej and Ingo Kuehne at Siemens Corporate Technology in Munich are […]
