This seems like a great technology for any low power, long life, remote sensing/telemetry application. I didn't see any information on recycling of this type of battery. Is end of life for one of these packs another disposal challenge in the making?
I seem to remember a few years back there was talk of a sensor system that had a very low current draw and was able to power itself via vibrations from outside. Sort of like the battery-free watches that I've seen. I wonder if that technology can be combined with a system like this to recharge with motion.
I agree with Rob, especially considering there have all ready been 39 reported shark attacks this year. It is good that this information is made available not only for aquatic applications but for many other applications that require long battery life due to limited access or charging. Good post!!
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
