>> In 2012, quadriplegic Jan Scheuermann fed herself for the first time using a robotic hand controlled by her thoughts. That was made possible thanks to a sensor wired into her brain that could read her neural activity. Now, scientists are working to shrink those sensors to the size of a grain of sand.

I'm Reuters reporter Ben Gruber. University of California Berkeley researchers are paving the way to the day where devices like Fitbit will be small enough to be injected into our bodies to monitor everything, from our blood sugar levels to our heart rate. Hardly visible to the naked eye, this is what so called neural dust looks like under a microscope.

Researchers have proven that these tiny implantable machines can record neural activity in rats in real time. The newest sensors don't require wires or batteries. They depend on ultrasound waves to power them as they gather data from the nervous system. The ultimate goal is to use these small sensors to help people who've lost motor control to regain it.

The technology is still years away from being available but it could be tested in people within the next two years.
