Just think about putting a tiny robot in your eye that will perform a procedure on retina to fix your vision. This may sound insane but its almost about to happen and this could be the next innovation in medical technology.
Scientist in Zurich, Switzerland are building almost microscopic robots to help with delicate surgeries. The bot has a retractable needle for probing and a body that is only a quarter-millimeter in diameter — which is the equivalent of about 4 human hairs. This means it's as thin as a surgical scalpel and its needle is just as sharp.
Imagining the size of the robot, any surgery could be non-invasive and minimal. Unlike a conventional robot, however, it is too small to carry any kind of battery or drive. To get around this, researchers developed a system called "The OctoMag," which uses a series of electromagnets around the patient's head to power the robot. Then, by slightly increasing or decreasing the force of the electromagnets, the robot is pushed or pulled through the body.
The system is not yet ready for humans, though researchers did conduct a first round of experiments with the technology by exploring the eye. The team in Zurich is looking to perfect it and hopes to shrink the nanobot to even smaller proportions.
