摘要： A wearable fluid metering device for delivering medication subcutaneously, intramuscularly or intravenously to a patient, includes a polymer actuator pump. The polymer actuator pump is flexible so it will conform to shape and yet can be used to rapidly displace a volume within a confined area. The actuator is much faster than prior art polymer actuator designs and can be actuated in multiple ways including introduction and hydration of the polymer matrix by a solution or the actuator can be actuated via pH change while it is in solution. The pH change can be made via electrical current such as that used in electro chemistry or the pH change can be made via a chemical change introduced to the actuator hydrating solution.
