Minimally Invasive Sensor for MRI Imaging Easily Implants Into Brain
Researchers at the Massachusetts Institute of Technology in Cambridge, Massachusetts (US) have developed a sensor that can be implanted in the brain without requiring power or a wired connection into the brain.
Researchers at the Massachusetts Institute of Technology in Cambridge, Massachusetts (US) have developed a sensor that can be implanted in the brain without requiring power or a wired connection into the brain. The device, which can detect tiny electrical currents in the brain and optical signals produced by luminescent proteins, interacts with an MRI scanner outside the body.
“Our device does not require a battery or an on-board power supply and is completely wireless,” MIT postdoc Aviad Hai describes the new MRI-based technique. “It opens the door to truly minimally invasive sensors that can even be injected easily to the brain.”
