The second innovation of the IntelliDrug system, namely the integration of a fully functioning and controllable microdosage system the size of two molar teeth, is the main focus of this chapter. Control of the system is accomplished using an osmotic pump, a flow-and fill-level sensor [6] and a valve to control the flow rate of the dmg out of the system. The programmability, addressed by IR communication through the cheek, allows the
