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)."

    If we ignore wear-out, battery replacement is obsolete.

    Uh hum.

      “Our system can run nearly perpetually if periodically exposed to reasonable lighting conditions, even indoors [...] Its only limiting factor is battery wear-out, but the battery would last many years.”

      By the time the battery wears out, you have gotten a few years of data; then you toss away the tiny thing.
