Nuclear power at small scale is already in use in devices. Some medical devices, smoke detectors etc. As long as there is proper shielding, the enclosure is robust enough, and the overall device is made easily serviceable, I'm all for it. I can understand the fear sentiment of anything flagged as radioactive, but radiation is all around us already. Idk, but the less we can ditch super toxic and explosive lithium the better.
The radioactive source isn't used for power in smoke detectors, it's used to detect smoke. What small scale devices use radioactivity actually for power?
My grampa had a pacemaker that was.

Edit2: For the smoke detectors, i know its not what powers it per se, as far as the electronics that sound the alarm and such. More pointing out it contains radioactive material, and is something in every (hopefully) house, and you likely walk by it often.

That is well cool
The issue is not the radioactivity, it's the power density. Per the article, this is ~24x smaller than an average phone battery, but can supply only 100uW.
I have a relatively conservative phone use, and on average, my phone uses 450mW. That means that you'd need 4500 of those batteries in your phone. But the battery would also need to cover the power usage peaks, which are multiple times higher than the average power consumption.
