By Albert van den Berg,Piet Bergveld

within the swiftly constructing details society there's an ever-growing call for for information-supplying components or sensors. The know-how to manufacture such sensors has grown some time past few many years from a skilful task to a mature region of medical learn and technological improvement. during this technique, using silicon-based options has seemed to be of the most important significance, because it brought standardized (mass) fabrication concepts, created the potential for built-in electronics, allowed for brand spanking new transduction ideas, and enabled the belief of micromechanical constructions for sensing or actuation. Such micromechanical buildings are relatively well-suited to achieve complicated microsystems that increase the functionality of person sensors. presently, various sensor components starting from optical to magnetic and from micromechanical to (bio)chemical sensors has reached a excessive point of class.
during this MESA Monograph the court cases of the Dutch Sensor convention, an initiative of the know-how origin (STW), held on the collage of Twente on March 2-3, 1998, are compiled. It contains the entire oral and poster contributions of the convention, and offers a good evaluate of the cutting-edge of Dutch sensor study and improvement. except Dutch paintings, the contributions of exterior invited specialists from Switzerland are included.
