Tiny ARM-Based Sensor System Makes Battery Replacement Obsolete

An anonymous reader writes "University of Michigan researchers have crammed an ARM Cortex microcontroller, a thin-film battery, and a solar cell into a package that is only 9 cubic millimeters in volume. The system is able to run perpetually by periodically recharging the on-board battery with a solar cell (neglecting physical wear-out of the system)."

    Batteries have a limiting lifespan.

    If they used a capacitor instead, this device would run virtually forever.

    Place this in a solid glass marble, and it might last forever too.

    If this device is as smart as TFS suggests, it can probably use more than 10 characters. Hell, something that size (9mm^3) could be, uh, discreetly placed to take pictures and send out the real thing!

    Not that I would ever condone or support such an act.
