A device uses electroosmotic assistance in the delivery of an active agent, such as drugs, to a biological interface. The active agent is delivered from a flexible impermeable reservoir by compressing the reservoir. The compression is caused by electroosmotically pumping fluid into a chamber that surrounds the reservoir, thereby increasing the pressure in the chamber. The increased pressure in the chamber causes the reservoir to compress and expel the active agent stored therein.
