Micro-Robot Capable of Working In The Body

Korean scientists have created the robots that are small enough to explore the human body and driven by the heart muscle.

Sukho Park at Chonnam National University, Korea, and colleagues have designed a micro-robots driven by the cell. Park team to make the robot with the heart muscle to grow the network from a mouse on the small-frame robots are made from polidimetilsiloksana (PDMS). PDMS is a polymer biokompatibel makes robots used in the appropriate application biomedik.

A special on robots this, Park said, is they do not require an external energy supply. But the cells of the heart muscle relaxation and contraction learner who provide energy. Muscle cells get the energy own heart from a glucose culture medium. Cells that beat themselves, allowing the robot moves six feet.

This robot has three short front legs (400 micrometer long) and three feet behind the longer (1200 micrometer long), all mounted on a body segiempat. At the heart cells learner contraction, the back legs longer bend into. This difference in friction between the front foot and back foot, pressing the robot move forward. The researchers measure the average speed of robots is about 100 micrometer per second.

Park said that robots like this crab can be used in the body cavity to clean up or clog the vessel, with a release agent solvent to clean the stoppage of them.
