Portable drug delivery systems present an opportunity to improve patient mobility and reduce drug dosage. Infusion pumps for drug delivery are heavily used in hospital and home care settings to administer a variety of therapies such as chemotherapy, antimicrobials, analgesia, anesthesia, and post-operative and chronic pain management. We are developing electroosmotic (EO) pumps for drug delivery applications. EO pumps offer active dosage control, are compact, use low power, and have no moving parts. We here explore a two-liquid EO pump that decouples the drug from the working electrolyte with a series of collapsible membranes and enables EO pumping of a wide variety of medications.
