Process sensors/ actuators embedding

MEMS technology also allows embedding of actuators and sensors in single reactor channels. Despite problems with temperature robustness, a solution must be found to transport the signals from the micro channels to the central process control system. To avoid a confusing cable set-up ( spaghetti conditions ), it is desirable to process the sensor data on-site, for example in an A/D converter, and to feed the digital data in a common bus system [13]. 

Most of today s efforts aim at proving the feasibility of the basic concepts a great deal of work will have to be done before smart materials can be applied safely to aerospace structures. The effects of embedded sensors and actuators on the mechanical properties of structures, the long-term stability of the sensing system and its survival during processing are just the first matters which will require careful evaluation. 

Complex embedded software systems are typically special-purpose systems developed for control of a physical process with the help of sensors and actuators. They are often mechatronic systems, requiring a combination of mechanical, electronic, control, and...
