It sounds like something from a science fiction film, but experts have created a ‘neural dust’ that can be implanted into the body.

The tiny wireless sensors will be placed in the body to track neural activity in real-time, to monitor people’s health from the inside.

The technology has been demonstrated successfully in rats and could be tested in people within two years, the researchers have now said.

The devices offer a potential new way to monitor or treat a range of conditions including epilepsy and control next-generation prosthetics.

‘You can almost think of it as sort of an internal, deep-tissue Fitbit, where you would be collecting a lot of data that today we think of as hard to access,’ said Michel Maharbiz, an associate professor of electrical engineering and computer science at the University of California, Berkeley.

Fitbit sells wearable fitness devices that measure data including heart rate, quality of sleep, number of steps walked and stairs climbed, and more. (Click to Article)
