Micromechatronics After Uchinos introduction of a new terminology Micromechatronics in 1979 for describing the application area of piezoelectric actuators the rapid advances in semiconductor chip technology have led to a new terminology MEMS (micro electro mechanical system) or even NEMS (nano electro mechanicalsystem) to describe mainly thin film sensor actuator devices a narrower area of micromechatronics coverage. New technologies product developments and commercialization are providing the necessity of this major revision. In particular the progresses in high power transducers loss mechanisms in smart materials energy harvesting and computer simulations are significant
