Tiny ARM-Based Sensor System Makes Battery Replacement Obsolete

Posted by timothy on from the transcend-batteries dept.

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.
