Researchers from the Ohio State University and Georgia Institute of Technology have discovered a way to send very small, “soft robots” into humans.
These could lead the way to less invasive surgeries as well as a delivery method for treatments for conditions ranging from colon polyps, to artery blockages, to stomach cancer.
Under their new system, doctors would steer the soft robot inside the body using magnetic fields. The robots are like a small actuator and because they are navigated wirelessly it makes their use far less invasive.
The soft robot is composed of a magnetic polymer; a soft composite that has magnetic particles mixed in which allows it to be controlled remotely by magnetic field.
This concept isn’t entirely new but the soft body of the robot is and this feature means less damage to the body traditional robots with hard bodies.
