A contribution on some basic definitions of sensors properties

HE continuous progress of the microelectronic technologies together with developments in material science has sustained the sensor area growth for many years. Contributing to sensor progress are advances in chemistry, biology, surface science, chaos and information theory, signal processing, nanotechnology, and simulation tools. All of these aspects, which are strongly pluridisciplinary in character, together with promising markets on the horizon in the fields of medicine, industrial processes, transportation, space, and food and beverage control, are contributing to the birth of the sensor science discipline. Moreover, the rather recent interests and efforts in many laboratories all over the world, in the DNA chip studies and genoma projects and in transgenic technologies, have enlarged even more the positive perspective of this rather young scientific domain. A positive consequence is its relevance and importance particularly in the development of social life in the near future. Some of the new branches of this revolution, for instance, bioinstrumentation, will certainly require more and more nanobiosensors which, although not yet completely identified, will certainly be promoters of new themes of advanced research and of needs of new fine technologies and nanometrology. In order to allow a coherent sensor development from both the scientific and technical point of view, it is necessary to promote an accurate dissemination of scientific information among all those interested in the sensor area. The knowledge of standards and that set of definitions, which have their roots into the branch of the measurement sci
