The application of fluidic systems to a variety of consumer devices would typically exploit fluidic structures of a few millimeters to a centimeter or so that are between the common fluidic realms of microfluidics and macrofluidics. For these devices power consumption, portability, batter operation etc. are significant factors in the design and implementation of these fluidic systems. However, the necessary range of fluidic device structures for electromagnetically driven high efficiency pumps, valves, switches, capacitors etc. require development to provide both the required functionality as well as to meet the user expectations for functionality, variability, cost, etc. but also lifetime, reliability, manufacturability etc. of the consumer devices exploiting these fluidic systems.
