| 摘要 | A device for metering fluids comprising a fluid chamber with one inlet or outlet port, at least one sidewall and a movable separator that is in contact with and separates the fluid in the chamber from the other components of the device, a porous actuator housing and wicking material, a flexible polymer actuator material in contact with the porous actuator housing and the moveable separator, an actuator hydrating solution reservoir with at least one sidewall, an inlet port, and in fluid contact with porous actuator housing, a fluid gate located at some point between actuator hydrating solution reservoir and the polymer actuator, effectively keeping actuator dry, and an external shell to hold all components so that the polymer actuator can only move in a direction and apply pressure to the separator in contact with the fluid in the fluid chamber, thereby dispensing fluid from fluid chamber. | ||||||
