<DIV>Smart sensors and micro electro mechanical systems (MEMS) can include a variety of devices and systems that have a high level of functionality. They may integrate sensing and actuating with information processing, analog to digital conversion and memory functions. Smart sensors and MEMS may respond to algorithmic instructions and calibration requests, allowing smart devices to become more autonomous as they provide self diagnostics and self correction. Intelligence enables adaptation, which in turn increases the reliability and longevity of the smart device and this can significantly reduce costs. The editors have brought together a roster of contributing experts to cover smart sensors including capacitive, inductive, resistive and image sensors, smart MEMS including power MEMS, optical MEMS, inertial MEMS, and MEMS print heads.</div>
