As humans, we tend to take the most powerful supercomputer in the world for granted: it has a roughly 38-petaflop processing capacity and 2.5 petabytes of memory (or 2.5 million gigabytes), yet only runs on a mere 12 watts of energy. And luckily, we all have one: the human brain. Only recently have silicon-based supercomputers caught up to the brain in raw computational power, with China’s 93-petaflop Sunway TaihuLight supercomputer coming online in June of last more

A new concept of a brain-computer interface has been proposed by engineering researchers at University of California Berkeley, utilizing what they term as ‘neural-dust’, tiny machines that would be implanted in the brain to help facilitate the collection of neurological data.

The tiny components would be powered by piezoelectric materials, of which produce an electric current when compressed, activated by ultrasound waves generated by a transmitter placed on the scalp. The implanted components would have a simple CMOS sensor that would measure the electrical activity being generated by the neurons around it, and re-transmit that back to the sensors on the scalp.
