We present a novel approach of designing and fabricating a non-invasive drug delivery device which is capable of delivering the drug to the target site in a controlled manner. The device utilizes a reservoir which can be reused once the drug has completely diffused from it. This micro-reservoir based fabricated device has been successfully tested using niosomes of insulin drug filled in, which was then sealed with a magnetic membrane of 20µm thick and was actuated by applying magnetic field. The deflection of the membrane on application of magnetic field results in the drug release from the reservoir...
