Scientists proposed "smart dust" concept, the future can real-time monitoring brain activity

In recent years, such as magnetic resonance imaging and positron imaging techniques can help people understand the real movement of the brain, they still exist several shortcomings, such as the radiation on the human body, and the image non-HD resolution, etc.. Recently, the University of California at Berkeley, researchers came up with the real-time observation of the human brain exercise methods - "smart dust."

 

Researchers point out, first of all they toward the cortex of the brain jet micro-electronic sensors which is as small as dust particles- "nervous dust" and then by ultrasound to supply power for these "dust" and remote control. According to the reports, each of the "nerve dust" is installed CMOS circuits , they are responsible for detecting the electrical activity of nearby nerves.

"Nervous Dust" is just a concept, not real. Now, they have to do is to create one of only 100 microns, can be in the noisy and warm environment of the body to send and receive signals particles. In addition, such a sensor also need to be connected to a piezo system so that it can put ultrasound into electronic signals. Of course, the system must satisfy two conditions: to provide sufficient voltage for the formation of ultrasound; but not affect on the brain.
