A flap valve magnetorheological micropump

A system comprising:

• a plurality of fluid delivery devices, each device comprising:
• a fluid chamber having a first end and a second end, the fluid chamber partially defined by a first one-way valve at the first end, a second one-way valve at the second end, a first wall comprising a magnetorheological elastomer, and a second wall opposite from the first wall, wherein the fluid chamber is movable between a first configuration and a second configuration;
• a plurality of electromagnetic actuators disposed adjacent to each of the fluid chambers of the plurality of fluid delivery devices, each electromagnetic actuator being configured to apply a magnetic field to deform the first wall towards the interior of the fluid chamber, close the first one-way valve, and open the second one-way valve, moving fluid in the flow direction;
• and
• a control system in electrical communication with each of the plurality of electromagnetic actuators, the control system configured to actuate the plurality of electromagnetic actuators in a pre-defined sequence to move fluid from one end of the plurality of fluid delivery devices to a second end of the plurality of fluid delivery devices.
