There are a lot of possible applications for shape memory actuators, but due to cost, so far they are mostly found in high-end areas such as space transportation. There is a company in Colorado which focuses on this, and has some parts on the International Space Station (http://www.ctd-materials.com/products/emc.htm).
Also, the Europeans have had a difficult time enforcing their electronics waste regulations. Apparently, some companies have decided that the penalties for illegally exporting waste to Third World countries are cheaper than the cost of complying with the regulations, particularly since they rarely get caught and when they do get caught the penalties are not always enforced. The BBC did a story on this last year (http://www.bbc.co.uk/news/world-europe-10846395).
Until the cost of shape memory actuators goes down, and/or the cost of failing to comply with regulations goes up, I don't see this technology catching on.
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.
