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?
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
