Abstract
Provided is a valve formed of a shape-memory polymer disposed in a flow channel, in which a flow of fluid in the flow channel is adjusted by deformation of the valve.
Claims18
A valve formed of a shape-memory polymer disposed in a flow channel,
- wherein a flow of fluid in the flow channel is adjusted by deformation of the valve.
A structure formed of a shape-memory polymer disposed in a flow channel through which biomolecules flow,
- wherein the structure is configured to have a deformation amount adjusted by controlling a heating condition.
A fluidic device provided with a valve formed of a shape-memory polymer disposed in a flow channel,
- wherein the valve is at least one selected from the group consisting of a normally open valve of which the state is deformed from an open state in which fluid flows through the flow channel to a closed state in which the flow of the fluid is blocked;
- a normally closed valve of which the state is deformed from the closed state in which the flow of the fluid in the flow channel is blocked to the open state in which the fluid flows through the flow channel;
- and a series valve which is formed by disposing the normally closed valve and the normally open valve in series.
A valve sheet on which a valve formed of a shape-memory polymer is disposed,
- wherein the valve is at least one selected from the group consisting of a normally open valve of which the state is deformed from an open state in which fluid flows through a flow channel to a closed state in which the flow of the fluid is blocked;
- a normally closed valve of which the state is deformed from the closed state in which the flow of the fluid in the flow channel is blocked to the open state in which the fluid flows through the flow channel;
- and a series valve which is formed by disposing the normally closed valve and the normally open valve in series.
