| Research Abstract |
In this study, we realized the channel opening and closing operation of the new micro-channel using the shape memory properties of cross-linked polycaprolactone. Shape memory properties were evaluated by the recovery by temperature change after patterning of the mold shape. As a result, the shape is stored in a slight pressure and recovery ratio was almost 100%. Then, a flow path by using a micro-pattern was prepared and the passage operation was studied using the local heating device. We found that the change of direction and the formation of the channel can be done by only the temperature change.
