Abstract
Microstructures of Poly dimethyl siloxane (PDMS) were driven by cultured cardiomyocytes of neonatal rats. The motion of PDMS micropillars actuated by cardiomyocytes, their force, and the mechanisms by which they attach to pillars were studied. Using scanning electron micrography, it was found that cardiomyocytes attach to the top of a pillar with a beating time of one in three seconds. The force of the cardiomyocytes was found to be about a few μN.
