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)."

    I think this is the first time I've ever actually seen a legitimate claim of a device drawing less power than it can charge from ambient sources.

      Never had one of those nifty solar calculators?

    "Neglecting physical wear" when it comes to batteries is like saying "This car runs forever (neglecting its need for fuel)"

    No, neglecting physical wear is like saying this car will constantly fuel itself, so it can run forever, until the engine or other components physically break down hundreds of thousands of miles later.
