I don't think that the batteries absorb radiation, since that would undoubtedly have an impact on their functioning. So there would be no reason for them to be considered as radioactive. Please know the facts before embracing more fears.
Beth, it does appear that the form factor is the main benefit of the flexible flat batteries, certainly not cost. But sometimes it does happen that engineering decisions are made based on something other than initial price. After all, not all products will be sold at WalMart. Sometimes quality or durability may trump purchase price. Really, it does happen.
So it appears the small size and flexibility of the lithium polymer batteries is what's driving the medical imaging sector to adopt this technology. There does seem to be a lot of tradeoffs and disadvantages as you outline in this piece. Is small size such a compelling reason that it trumps some of the potential pitfalls?
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
