Abstract
A newly muscular cells stretching system which improves output of bio-microactuator that driven by the contractile force of muscular cells is developed. Using conventional model, muscular cells are stretched only one or two linear directions, in contrast arched muscular cells stretching system has a new structure which stretches cells circumferential direction. It enables to produce a bio-microactuator which has new structure. The muscular cells are cultured on the thin film made of PDMS and elongated and contracted by using an external magnetic field as driving source. As a result, we realized that cells culture in totally closed and safe environment for cells. We conducted fundamental experiment with using cultured skeletal myoblast and observed change in cell orientation.
