They are working on putting it in pacemakers, but apparently it doesn't scale up.

"The amount of carbon-14 you'd need to power a cell phone would ... require a mass greater than the phone itself."

The second thing is that this is a major game changer. We now have efficiencies where this becomes commercially relevant. It would still be considered a microbattery, but say for example, 200 microwatts. That's how much energy is needed to power a pacemaker.

Quote
For a single microwatt, we're talking about something 4 mm x 4 mm (0.15 x 0.15 in) in width and length, that's very, very shallow. The size of a fingernail, but thinner. You can mechanically stack these in any number.

Quote
Well, a device that's 10-mm (0.39-in) square, and less than 0.5 mm (0.019 in) in depth, would yield tens of microwatts. The amount of carbon-14 you'd need to power a cell phone would be about the size of a tub of vegetable spread. It can be done, but the physical bounds of carbon-14 diamond would require a mass greater than the phone itself.

So nothing has really changed here.

AA battery = 50x14mm = 2500mm2
4x4x0.5mm claimed 1uW = 8mm2
So theoretically a perfectly packed AA battery would be ~300uW. Which is not bad, but realistically with the supercap and other stuff in there, ~100uW sounds about right.

 :-DD  Well it depend what are you want to do with that energy. A Traditional Smartphone draw a lot of power for sure. There you can replace then but a Pacemaker? Do you want get cut open for a recharge?  :scared:

It's almost as if you don't know you can charge phones wirelessly these days.

Sure I do but when there is a huge power outage like a Hurricane would you like hear a beep who maybe indicate that you should recharge your pacemaker?

Looks like NDB has patents issues now. Arkenlight has the diamond patent.

They don't actually recharge them AFAIK. The pacemaker is under the skin near the surface and they replace the entire thing every ten years, battery and all.

And (b): Modern pacemakers are passive. They only kick in when they detect your heart going out of rhythm. You can live perfectly without one so long as you don't do anything strenuous like fighting off zombies.
