Abstract
A pumping assembly is provided. The assembly includes a first movable element selectively movable within a first pump housing and an actuator including an active material. The active material is configured to undergo a change in attribute in response to an activation signal. The active material is operatively connected to the first movable element such that the change in attribute causes the first movable element to move within the first pump housing. In one example, the active material is a shape memory alloy material having a crystallographic phase that is changeable between Austenite and Martensite in response to the activation signal.
