Patent ID: 8337457

Claim:
An apparatus, comprising: a reservoir for containing a fluid; a first actuator having a first configuration and a second configuration, the first actuator configured to exert a first force on the reservoir when the first actuator moves from its first configuration to its second configuration such that a first volume of fluid within the reservoir is communicated out of the fluid reservoir; a transfer structure disposed between the first actuator and the reservoir, the transfer structure having a surface configured to engage the reservoir such that the first force exerted by the first actuator is distributed by the transfer structure across a surface of the reservoir engaged by the transfer structure; and a second actuator including an electrochemical actuator having a first configuration and a second configuration, at least a portion of the second actuator configured to deflect such that the second actuator exerts a second force on the reservoir when the second actuator moves from its first configuration to its second configuration such that a second volume of fluid within the reservoir is communicated out of the fluid reservoir.
