Bi-layer artificial muscle valves for drug delivery devices

Abstract

In this paper, a "responsive drug delivery system", in which a sensor measures a marker in the patient's body and releases medication the patient requires at any given moment is developed. In this way, we can precisely control the drug concentration in patient's body to enhance drug efficiency and lessen side effects. In order to achieve responsive drug delivery, a reliable release device (e.g., a valve) has to be developed. Biocompatibility, low energy consumption, minimal and no leakage are the main requirements for such a release method
