1. A shape-memory alloy wire pumping system comprising:
at least one shape-memory alloy wire;
a pump plunger connected to the at least one shape-memory alloy wire wherein the shape-memory alloy wire, when actuated, actuates the pump plunger;
a valve member connected to the at least one shape-memory alloy wire wherein the shape-memory alloy wire, when actuated, actuates the valve member;
a controller for controlling an ontime of the at least one shape-memory alloy wire; and
a temperature sensor for determining the temperature of the shape-memory alloy wire wherein the controller determines the ontime based on the temperature of the shape-memory alloy wire.
