Tired of hearing about robots that digest slugs for
about a robot that powers itself by sucking the bodily fluids from
Heller and other chemists at the Universty of Texas, Austin have developed a
new fuel cell which generates electricity from the glucose-oxygen
reaction that occurs in human blood. The actual purpose is fairly benign
- powering medical sensors and animal
tracking devices. The power output is limited but enough for CMOS
devices. A summary of the technical
specs (PDF format) for the prototype are available online.
I imagine lots of nano bots living off and floating in your blood and
to keep your nano bots alive, which ultimately keep you alive, you need
an occasional infusion of fresh blood by inserting your fangs into an
The fuel cells to degrade over time, something like 6% per day.
So then the nano-bots would have a limited lifespan before their fuel
cells quit. Then the body would have to digest, break them down, or
expell them somehow. Hummm...sort of like the nano-bots on
the "Andromeda" TV show. After they've performed their task, they go
away. Of course, if the bots know their power source is going, at a
certain point the bots would stop and head for the bladder or
intestines or stomach to be digested or excreted.
