That's a really good point, Mydesign. I think this self-healing effort is a good one as well, though, because it will help these batteries last longer in general so they don't have to be replaced. Some people have argued that it's not often long-lasting batteries are replaced but I beg to differ. But you're right, to increase the actual usage time of a battery--ie, how long it holds its charge--is probably an even more important aspect of batteries to be working on.
"The other day I saw a video on these self healing materials, and I was amazed by this invention. Certainly it can find numerous applications in the engineering world specially in the polymer industry."
Taimoor, what's the specialty in polymer industry?
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
