Nano devices are the wave of the future if scientists can discover a way to deliver power to them. Imagine a patient with heart problems that the doctors don’t want to cut open for fear of making those problems worse. Now imagine they simply inject a nano device into him and have it cruise through the heart to do all the diagnostic work without issue (a nano device is smaller than a human hair so there would be no risk of damage).
That’s a possibility in the future but to make it happen a power source is needed for those nano devices so they can be independent. That power source is coming in the form of nano batteries. They’ll have technological and scientific benefits far beyond medical practices, too. In fact, the possibilities are limitless with nano devices and that should excite everyone, not just fans of technology.
