Abstract
A motor-less pump includes: (a) a housing having an inlet provided to allow fluid flow into the housing and an outlet provided to allow fluid flow out of the housing; (b) an elastic diaphragm positioned in the housing such that motion in the elastic diaphragm drives the fluid flows at the inlet and the outlet of the housing; and (c) one or more electromechanical polymer (EMP) actuators each being provided on a surface of the elastic diaphragm, wherein the mechanical responses to electrical stimuli applied on the EMP actuators cause the motion in the diaphragm. The EMP actuators may include one or more bimorphs.
