Abstract
The present invention provides systems, devices, and related methods, involving electrochemical actuation. In some cases, application of a voltage or current to a system or device of the invention may generate a volumetric or dimensional change, which may produce mechanical work. For example, at least a portion of the system may be constructed and arranged to be displaced from a first orientation to a second orientation. Systems such as these may be useful in various applications, including pumps (e.g., infusion pumps) and drug delivery devices, for example.

152. A device for delivering a therapeutic to a patient, comprising:
-
a fluid reservoir; and an electrochemical actuator including an electrode configured to deflect as the electrochemical actuator undergoes a change in electrical potential, the deflection of the electrode being operative to cause fluid to be delivered from the fluid reservoir. - View Dependent Claims (153, 154, 155, 156, 157)

158. A device for delivering fluid to the body of a patient, comprising:
-
a fluid reservoir; and an electrochemical actuator having a bimorph electrode and configured to change volume or position as the electrochemical actuator undergoes a change in electrical potential, the change in volume or position of the electrochemical actuator being operative to cause fluid to be delivered from the fluid reservoir. - View Dependent Claims (159, 160, 161, 162, 163, 164)

165. A device for delivering a therapeutic to a patient, comprising:
-
a fluid reservoir; a housing suited for removably associating the fluid reservoir with the body of the patient; and an electrochemical cell including a negative electrode, a positive electrode, and a species formulated to intercalate, de-intercalate, alloy with, oxidize, reduce, or plate with a first portion of the electrochemical cell to an extent different than a second portion of the electrochemical cell, thereby imparting a differential strain between the first and second portions and causing a displacement of at least a portion of the electrochemical cell, the displacement being operative to cause fluid to be delivered from the fluid reservoir. - View Dependent Claims (166, 167, 168, 169, 170, 171)
