How Smart Dust Could Spy On Your Brain
Intelligent dust particles embedded in the brain could form an entirely new form of brain-machine interface, say engineers.
Today, Dongjin Seo and pals at the University of California Berkeley reveal an entirely new way to study and interact with the brain. Their idea is to sprinkle electronic sensors the size of dust particles into the cortex and to interrogate them remotely using ultrasound. The ultrasound also powers this so-called neural dust.
That ultrasound is a big hangup [not to mention the sprinkling] but what would you expect from spies?
Photons [light, people] is where it’s at.
But imagine lighting up the dark recesses of Dick Cheney’s mind.
Some things, like nuclear annihilation and reading Dick Cheney’s mind, are just too horrible to contemplate.
Welcome to our Brave New World.
