摘要
A device for opening or closing a fluid flow path comprises: a fluid inlet, wherein the fluid inlet comprises one end of the fluid flow path; an inlet covering, wherein the inlet covering is adjacent to the fluid inlet; and a material, wherein the material is capable of expanding or contracting via a change in temperature; wherein the expansion or contraction of the material causes movement to the inlet covering, and wherein the movement of the inlet covering either opens or closes the fluid flow path. A method for opening or closing a fluid flow path using the device comprises: allowing or causing a change in temperature to the material.
