Non-invasive drug delivery is an upcoming area in personal health care for localized drug delivery. Iontophoresis is one of the most widely used techniques used for non-invasive drug delivery. Typically Iontohoresis devices are expensive or bulky or both. With this device designed and developed for IDBR, we have made the device at less than 50% of the cost of other comparable products.
Iontophoresis requires precision constant currents in the range of uA to mA under varying load (body resistance) conditions. Hence the project needed a combination of precision instrumentation, constant current sources and saftey features like optically isolated H-Bridge for current direction controls.
