Miniaturized, integrated sensors and actuators called microsystems are a rapidly growing field with great future potential. In order to promote their use further, specialists must make them more accessible to system designers at all stages of development. This can be done through behavioral modeling of sensors and actuators which can be used in conjunction with models of the associated electronics to simulate a complete microsystem. Additionally, models of microsystem components realized during modeling and simulation can be retrieved for use in the assembly phase of manufacture. Here virtual- reality environments are used to aid in the realization and use of automated robot systems working with miniature components in the micron scale. The use of computer aided design and simulation tools in this field is critical owing to the high prototyping costs. Data exchange between the various systems is advantageous and reduces design and manufacturing costs while speeding up time to market.
