Dust-sized sensors that can be implanted within the body

        This might sound really creepy at first, but the technology made possible through it is endless. Engineers from Berkeley have created these sensors, which they call “neural dust.” Both commercial and medical implications of such a small sensor are exciting.

    Essentially, these micro-sized sensors require no power and can be implanted directly onto a nerve or muscle fiber. The technology could power the health-monitoring Fitbits of the future, or even help treat diseases such as epilepsy and internal inflammation by “stimulating” nerves and muscles.
