Bi-layer artificial muscle valves for drug delivery devices

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
