View Medical News Microrobots made from heart muscles [1/0] Vote Up Vote Down http://www.primidi.com/2007/09/02.html#a1944 Submitted by allen 10 months, 2 weeks, 5 days, 19 hours ago We have imagined for a long time that microrobots will be able one day to monitor or repair our biological systems -- but with limited success (check A robot that travels through the body for example). Now, South Korean scientists have built robots small enough to roam the human body and powered by living heart muscle. These hybrid cell microrobots move like crabs, with their 3 short front legs (400 micrometers long) and their 3 longer back legs (1,200 micrometers long). According to one of the researchers, 'these crab-like robots could be used inside the body to clear blocked tubes or arteries.' According to Chemical Science, Sukho Park of the Nano/Micro System Laboratory at the Seoul National University and his colleagues "made the robot by growing heart muscle tissue from a rat onto tiny robotic skeletons made from polydimethylsiloxane (PDMS)."
