Scientists in Korea have created a robot small enough to be able to explore the human body and is driven by the heart muscle.Sukho Park of Chonnam National University, Korea, and colleagues have designed a micro-robot driven by the cell. Park to create a robot team is a network with the heart muscle from a rat in the framework of small-robot framework that is made from polidimetilsiloksana (PDMS). PDMS is a polymer biokompatibel thus making the robot suitable in practice biomedik.
A special on the robot, said Park, is they do not require an external energy supply. But the cells of heart muscle berelaksasi and berkontraksi that provide energy. Cells-heart muscle cells themselves get energy from a glucose culture medium. Cells pulse itself allows this robot is the sixth foot.
This robot has three legs before the short (length of 400 micrometer) and three feet behind the longer (1200 micrometer long), all mounted on a square body. At the heart cells berkontraksi, the back foot a longer bend to the inside. This difference in friction between the front foot and back foot, pressing the robot move forward. The researchers measure the average speed of robot is about 100 micrometer per second.
Park the robot-crab-like robot that can be used in the body cavity, or to clean the choke tube, with a release agent solvent to clean the stoppage of their skip.
