Abstract
A jet dispenser is provided with a giant magnetostrictive actuator which expands or contracts in response to electric currents. A set of flexural elements is coupled to first and second ends of the giant magnetostrictive actuator and flexes when the giant magnetostrictive actuator expands or contracts. The jet dispenser further comprises a chamber containing fluid and the fluid is dispensable through a nozzle which is in communication with the chamber. A piston coupled to the set of flexural elements is slidably located in the chamber and is actuable by flexion of the flexural elements to apply a force against the fluid for dispensing fluid through the nozzle.
